HI, Randi - I found my boys liked the flavour of Royal Canin better. They now get it as their wet food - and I just mix it with a fork with very hot water from the faucet. These days they are getting Omega 3 - 6 oil in with it. It's about a 1/2 tsp of water, and they get more moisture that way too - even though they have no kidney problems as yet.

Maybe mixing just a tiny bit of "stinky" food in with it would tempt him?

Good luck at the vet's..I hope his appetite perks up.
