I have two siamese mix cats that are from the same liter, one of them is fine health wise, but the other, he's been losing weight for the past year, he's looking really skinny.
We have another siamese from the same mother, but he's only five and he's really obese.
We took Josh, (The skinny kitty) to the vet and got blood tests done. We got him checked for feline leukemia and he tested negative. They couldn't tell us what was wrong with him. He's the same happy cat on the outside, but I don't know if he's suffering.
We took both of our dogs to the vet the other day for shots, to be weighed, and to get one of their ears checked out, and we brought up that we had an obese cat, and the vet asked if we gave him dry food, and we do. He said that dry food has something in it, that can cause heart decease (sp), or something like that, obesity, and some other things. He told us that we can start feeding them wet food, as well as dry food. So we bought some, and they all like it. Are we doing the right thing? Will this help Josh gain some weight!?
Also! Josh has had this little lump on the side of his neck since he was born, we had the vet look at it, and we asked him if it could be a tumor, or if it had something to do with cancer, he said he doubted that it did. Should we get a second opinion? We really can afford to get it taken off, or treated if it's going to cost us thousands of dollars, do we put him to sleep if this happends?

He seems to be getting better, but we really aren't sure!
Please help!
