Well, this is interesting to say, but... I think TetraFin, yes, the fish-food company, should start designing some cat treats.
At first I thought my cats were weird, because they couldn't resist the stuff. But then I looked at the ingredients and found that it contains three different types of fish meal, some shrimp meal, and amino proteins... stuff cats love! Odd that its in fish food, but great for my kitties! They like it more than their normal food, and in small doses, I've noticed their coats having a glossier texture and their, well, they seem much more amiable. I have a tabby and my sister a siamese, and they both look great. I thought that Tetrafin should use the same stuff for kitty treats. They might make some money! Try it at home; I'm no health expert, but it seems like a good idea
