When you adopt your new cat. This can be a stressful time for them as they're being displaced. We strongly recommend to at least use one bag or 12 cans of their existing food to transition them to whichever food you decide to feed them to put the least amount of stress on them and to avoid having them not eat when they enter your home. At Catoro, we believe in feeding our cats the best quality food we can find to keep them healthy and happy. Everything we offer online is what we feed our cats in store.
