not suitable

notThe smell is terrible. The cat not only refuses to eat it on its own, but even if you try to mix it with regular food, it gags and tries to vomit. It's awful

Too big

My sweet old man has a bad case of a runny nose and sneezing. The vet recommended Lysine treats. I ordered these and the treats are really big of a cat. Broken it in half and he only ate half and left the other half. Would not touch it if unbroken and stopped eating them altogether. He seems to prefer the other brand I purchased when I mix it with a few other treats.

Big but Helpful

My cat won't eat them unless they are broken into at least 3 pieces but I'm fine doing this as we can't do L lysine powder! My cat loves them

The actual chewable is too big. I've been breaking it into 4s and mixing it into the kibble. The cat actually ate it for a few days. That was short lived. I have now found them remaining uneaten in the bottom of the dish. It DID seem to be working when he was taking it regularly. Will keep hoping
