My 6yr old Jacob is not well? Please help..

[FloridaChic]

Thanks so much, I am going to try to see if the VET will lower the cost for me, I think that the price is a little high, but here is to hoping

Jacob is the tabby and Nitro is the black/white cat.
They are both 6 years old, only a couple weeks apart.
We adopted them when they were 4 months old, they were together in a cage since birth (not brothers) and we had to take both, they just loved each other and still do!
