Auntie Crazy is right.
With a kitty that is prone to crystals or bladder issues, you cannot, feed fishy stuff, or fishy flavored foodies. Bump won't eat wet. Period. To increase his water intake, he gets 1 teaspoon Gerber baby food, chicken or turkey ONLY, mixed with water, so its like a broth, twice a day, and this is per my vet, mol. He loves it, and I do this with the others too, as I don't need another kitty with crystal or urinary issues.
I understand, if Macy does not like or cannot/will not eat Blue Wilderness, but there are other grain free foodies out there. Grains are one, of many, and the most common, cause of crystals. C/D is full of them.
The reason vettys put kitties on C/D and S/O, is because, they are high in salt, which ya know, if ya eat something that is real salty, it makes you thirsty, so ya drink more. Which is what these foodies are trying to achieve, and they are on the right tract, trying to increase the water they take in, BUT, it really, is not enough, and there are much safer ways, to increase their water intake. Heart kitties cannot, has foodies, that is high in salt.
Hey, there is a cat show, in Brockport, Oct 22 and 23. I won't be going, Cowboy brought home something from the show in Syracuse, and it hit hard and fast, I had 3 down, at one point, plus myself, it strikes within 4 days of exposure. Not going to take the chance of exposing him or any of them, as he would be seeing most of the same cats, we is on lay up for a few months, mol.
