|You can try different wet food brands for variety. For my cats, (I have 6) I put a dab of three different kinds on a plate so they have little samples of each. They love that. Some choices are more popular than others though. None of them would eat a whole 3 oz can by themselves though before they got tired of it and walked away. Some will go back and finish, others will not touch it again after walking away. One tries to bury it.
Bury it - that is so cute!
We have three kittens and we do something similar - I always bring up three different flavours of food to feed them. They all start out with their original and when they get bored, they move on to the next flavour. I agree with what others have said - it sounds like he is just bored of his wet food. Change things up, see if that helps. I know our kittens (who normally LOVE their wet food) have their favourites of the flavours, and when they got bored of their normal food, I just bought a different group of flavours and they were fine again.
