Well, the only thing I can tell you, that I know for a fact, is that it is one of ingredients, in Blue Wilderness. Even tho Bump picked it, his cardiologist at UC Davis, had to approve it, because of his issues. His cardiologist approved it. He would not have approved it, if he felt, any of the ingredients were not safe for him. I also know, this is a cat, who at 10 months old, was not supposed to live past 1 yr old, per 2 other cardiologist's. He is now 5 yrs old, and doing very well. He looks great and acts great, and runs thru the house at warp speed, with the kittens, and his vet and his cardiologist, let him go back on the circuit, and even tho he was in 1st place, in his Region, when they pulled him, he still finished in the Top 10, missing all those shows.
You are right. There are many things, that people, dogs, horses can have, that cats can't. And with Bump's issues, there are many things, he cannot have, that a normal cat can have. His vet, his cardiologist, are extremly careful, with what he can and cannot have, beyond careful. Everything, a normal cat would be given, has to be checked, that is is safe for Bump. They also know, how Bump's mommy is, m-o-l, another reason for them to be sure, m-o-l.
Here is a link, from the list of ingredients, from Blue Wilderness. Yucca is an anti inflamatory. If I thought, for one second, that Yucca was not safe for Bump, I would be "thee very first one" to make a stink about it. And we all know, what the big Bump's mommy, can do, m-o-l.
(only cause, the baddy Lola, took away, my machine gun, m-o-l)
Where is our Merry New Years stuff?
