Terms of Use
Last updated · October 17, 2026
These terms govern your use of the PetFoodPrices website and everything published on it (the “Service”). By opening or using the Service, you agree to them. If you do not agree, please do not use the Service.
1. Provider
The Service is provided by Dr. Jan Philip Wahle and Lars Benedikt Kaesberg, Siedlungsweg 24, 37124 Rosdorf, Germany. Contact: [email protected]. Full provider identification is in the Imprint.
2. What the Service is
PetFoodPrices is a free, advertising-financed price-comparison site. It retrieves pet food listings from Amazon, reads net weights, can and pouch counts and stated energy values out of them, and ranks the listings by a computed price per kilogram of net weight, with the price per 1,000 kcal beside it. How that is done is described in the methodology.
Purina, Royal Canin, Hill’s, Pedigree, Whiskas, Felix, Blue Buffalo, Greenies, Inaba and other names of manufacturers and their product lines are trademarks of their respective owners. We use them only to identify the products listed (nominative use). Their use implies no affiliation with, endorsement by or sponsorship from any manufacturer, and we are not a manufacturer of any product listed here.
The Service is informational. It is a reading of publicly available listing data, produced automatically, and offered on a best-effort basis. You are not required to register, and no account, contract or ongoing obligation arises between you and us from browsing the site.
3. No warranty for prices, weights, energy values or rankings
Prices change constantly and what Amazon shows at checkout is what applies. Figures on this site are snapshots from the last synchronisation, not offers, not quotes, and not a guarantee that a product is available at that price, in that pack size, or at all.
Net weights, can and pouch counts, energy values and the statements “complete” or “complementary” are read automatically from listing text written by sellers and manufacturers; pounds and ounces are converted at 453.592 g and 28.3495 g. Energy is the metabolisable energy the label states; where a dry food states none, the Service substitutes a typical value for dry dog or cat food, marks it with a tilde (~) and never does so for wet food. Whether a food is complete or complementary is taken from the seller’s own statement under the FEDIAF guidelines (Europe) or the AAFCO nutrient profiles (United States); we do not verify it. Veterinary diets are listed without a ranking. Subscribe-and-save, coupon and other conditional prices are not used: the price shown is the listing’s one-time price at the last synchronisation. Parsing can misread, listings can be wrong at the source, and a price per kilogram is only ever as good as the label behind it.
To the extent permitted by law, we therefore give no warranty that any price, net weight, can or pouch count, energy value, protein figure, complete or complementary statement, ranking, availability indication, rating, currency conversion or derived metric is accurate, complete, current or fit for any particular purpose, and no warranty that any category, listing, country or feature will remain available. Verify anything that matters on the product page itself before you buy. Section 15 governs liability; nothing in this section limits liability where the law does not allow it to be limited.
4. Not veterinary or feeding advice
PetFoodPrices compares prices. It does not recommend a food, a diet or an amount to feed, and nothing on it is veterinary, nutritional or other professional advice, diagnosis or treatment. The feeding amounts and daily costs in our calculators come from a textbook estimate of resting energy needs and a factor you choose; they are informational only, and an individual animal’s needs differ with its age, breed, activity, health and the food itself. Whether a food is complete or complementary is the seller’s statement, not ours. Veterinary diets are meant to be fed under a veterinarian’s supervision; we list them without ranking them, and a lower price is no reason to switch. Talk to your veterinarian before you change your animal’s diet, and never disregard or delay veterinary advice because of something you read here. If you suspect an emergency, contact a veterinarian immediately.
5. We are not the seller
We do not sell, ship, import, distribute or stock any product shown on this site, and we are neither the manufacturer nor the feed business operator behind any listing. Every purchase is a contract between you and Amazon or the respective third-party seller, on their terms. Net weights, energy values, feeding guides, ingredient and analytical statements and the description of a food as complete or complementary are statements of that seller or manufacturer, not ours. Payment, delivery, returns, warranty, product safety, labelling compliance and any claim arising from a product are matters for that seller and manufacturer, not for us.
6. Advertising and affiliate links
Outbound product links carry an Amazon Associates tag and are marked as advertising. As an Amazon Associate we earn from qualifying purchases, at no additional cost to you. That is how the Service is financed. Rankings are computed from the data alone; placement is not for sale, and no manufacturer, brand or seller pays for position, inclusion or exclusion.
7. Permitted use
You may use the Service for your own personal, non-commercial purposes, and you may link to it freely. Search engines and AI assistants are welcome to crawl, index, summarise and quote individual figures with attribution and a link to the page they came from — that is the point of publishing a number nobody else computes, and our robots.txt says so.
You may not, without our prior written consent:
- systematically extract, copy, scrape, harvest or re-utilise substantial parts of the catalogue, the computed metrics or the underlying database, whether in one operation or by repeated extraction of insubstantial parts;
- republish, redistribute, resell, sublicense or build a competing price-comparison product from the data;
- access the Service by automated means beyond ordinary crawling, or in a way that circumvents rate limits, caching, access controls or the directives in
robots.txt; - frame, mirror or present the Service as your own, or remove, obscure or alter attribution, affiliate tags or advertising markings;
- reverse-engineer, decompile or disassemble any part of the Service, except to the extent such restrictions are prohibited by law;
- use the Service unlawfully, to infringe the rights of others, or in a way that impairs its availability for anyone else.
8. Our rights in the site and the data
The Service, its category model, its normalisation methodology, the metrics it computes and the compiled collection of listings behind them are protected by copyright and by the sui generis database right under Sections 87a et seq. UrhG (Directive 96/9/EC). We are the maker of that database. Except for the permitted uses in Section 7, all rights are reserved. Nothing on this site grants a licence to any trademark.
9. Third-party content and trademarks
Amazon, the Amazon logo and related marks are trademarks of Amazon.com, Inc. or its affiliates. Brand and product names are the trademarks of their respective owners and are used for identification only. Their appearance here does not imply any affiliation with, sponsorship by, or endorsement from those owners.
10. External links
The Service links to external sites, principally Amazon marketplaces. We have no influence over their content, terms or privacy practices, do not adopt them as our own, and accept no liability for them. Once you follow an outbound link, that site’s terms and privacy policy apply.
11. Availability and changes to the Service
The Service is provided free of charge on a reasonable-effort basis. We give no uptime guarantee and are not responsible for outages caused by Amazon, our hosting, our upstream data providers, your network, or other services outside our control. We may at any time add, modify, suspend, restrict or discontinue individual categories, countries, metrics, features or the Service as a whole, including for technical, legal, commercial or data-licensing reasons — for example if a data source changes its terms. You have no claim to the provision, restoration or continuation of any particular feature, figure, category or country.
12. Beta and experimental figures
Some figures are explicitly marked as estimates, derived values, or experimental. They are provided as-is, may change or disappear, and should be treated as an indication rather than a result.
13. Your conduct
You are responsible for the searches you run and for what you do with what you find. Do not use the Service to build, verify or distribute claims about products that you have not checked at the source.
14. Indemnification
To the extent permitted by law, you will indemnify and hold us harmless from third-party claims, losses, damages, liabilities, costs and expenses (including reasonable legal fees) arising out of your breach of these terms — in particular a breach of Section 7 — your unlawful use of the Service, or your infringement of third-party rights through use of the Service or its data. For consumers (Verbraucher within the meaning of Section 13 BGB) this applies only to the extent permitted by mandatory consumer-protection law and only where the claim is attributable to your fault.
15. Liability
We are liable without limitation for damages caused by intent or gross negligence, for injury to life, body or health, under the German Product Liability Act (Produkthaftungsgesetz), and under guarantees we have expressly given. For slight negligence we are liable only for the breach of essential contractual obligations (cardinal duties), and that liability is limited to foreseeable damages typical for a service of this kind. All further liability is excluded to the extent permitted by law.
Because the Service is provided free of charge, our liability is in any case governed by Sections 521 and 599 BGB where those provisions apply. Subject to the preceding paragraph and to the extent not already excluded, our aggregate liability for all claims arising out of or in connection with the Service or these terms is capped, per affected user and per twelve-month period, at one hundred euros (EUR 100).
In particular, and to the extent permitted by law, we are not liable for a purchase decision made on the basis of a price, weight, energy value or ranking shown here, for a price that changed between synchronisation and checkout, for a listing that was misparsed, unavailable or withdrawn, for indirect or consequential damages, or for lost profits or savings. Section 4 applies to any decision about what, how much or whether to feed an animal. This allocation of liability also applies in favour of our legal representatives and any persons acting on our behalf.
16. Changes to these terms
We may update these terms to reflect changes in the Service or in the law. The current version is always available at this URL, and the date at the top says when it last changed. Continued use after a change means you accept the updated terms.
17. Governing law and jurisdiction
These terms are governed by the law of the Federal Republic of Germany, excluding its conflict-of-laws rules and the UN Convention on Contracts for the International Sale of Goods. If you are a consumer habitually resident in the EU, you retain the protection of the mandatory provisions of the law of your country of residence. Where a place of jurisdiction may lawfully be agreed, it is Göttingen, Germany.
We are not willing or obliged to participate in dispute-resolution proceedings before a consumer arbitration board. The former European Commission online dispute resolution platform was discontinued on July 20, 2025.
18. Severability
If any provision of these terms is or becomes invalid or unenforceable, the remaining provisions stay in force. The invalid provision is replaced by the statutory rule that comes closest to its commercial purpose.
