Frequently asked questions

Is Costco Kirkland WSAVA-aligned?

Costco Kirkland is not on our WSAVA-aligned shortlist. That doesn't automatically mean the food is poor quality — many strong brands haven't pursued WSAVA recognition — but it means we lack independent confirmation of feeding-trial validation and on-staff veterinary nutritionist staffing.

Has Costco Kirkland ever been recalled?

We haven't matched any Costco Kirkland products to current FDA recall records. Note that absence of matches isn't a guarantee of no recall history — older recalls may not be in the current feed.
