Is it safe to give my cat tuna or sardines as a food substitute?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered

When I run out of cat food I give my cats either tuna in water or sardines in tomato sauce, whichever I happen to have on-hand. This happens about once every two months. Is there one of those I shouldn't give them? Or should I give them one over the other if I have both? They haven't had any I'll effects to either (and prefer sardines).

If your cats have not had any issues with either product then they are probably ok for a treat occasionally for your kitties. The sardines if they contain bones may pose a slight risk as occasionally we can see obstruction or damage to the esophagus or stomach due to bones. If the sardines in tomato sauce have garlic or onion in them, they would not be recommended. Neither food would be recommended as a sole diet however as they wouldn't be a complete and balanced diet for your kitty.
