I started reading online
and found that many
cats are allergic to the fillers
in cat foods, so I switched him to Natural Balance. No change in the vomiting, but his coat is much more silky. Several months later, after hearing really good things about Blue Buffalo, I gave that a try. Again, no change. Back to reading, I found that probiotics might help, so I tried mixing some in with a little wet cat food (he usually only eats dry cat food). He just sniffs it and walks away.
