I have a sweet little Cornish Rex kitty who weighs about 8.5 pounds. I feed her both dry and canned food each day. The canned food is a very small amount twice a day - about half a tablespoon morning and evening. Thus, getting through a 3 oz can takes a long time. I have read one should only store canned food for 2-3 days. In my case, it could last for a week or more. Can I freeze some of it? Does anyone else have this problem?
