Cat food has a nice initial taste, but then a bad after taste. Same with dog food. I`m sure it is the case for any brand, but I haven`t tried them all. Some dog treats aren`t half bad though. Fish food is ok. The flakey stuff that is. I haven`t tried the pellets. I`d have to say though, that strawberry flavored gerbil treats are the best. The little yogurt-like gerbil drops you buy at the store for them, mmm. I think that`s all that I`ve tried though. I`m not brave enough to try my hermit crab`s food, that looks nasty.
