Diane,
Do you mind if I pick your brain for a minute ?
Was Tyler always a big boy or did his weight come on gradually ?
I was a little surprised when Claudio got his dx. He had none of the usual s/s of a diabetic cat.
They say cats lose weight before they get a dx.
Claudio never lost any weight. He has stayed large for the most of his life.
And since I fed raw, his portions were always controlled. He is eating FF now due to the lack of fresh meat in the stores. He never went on the hunt for more food.
The only thing I can deduce is that I give him too many treats at test time.
I give either a sardine, or about 7-8 pieces of cooked diced chicken(about the size of regular treats), or a teaspoon of tuna.
Could I be giving too much treat wise ?
He is, like you said.... a blob, lol
