my cat drooling and acting wierd

my cat is around 1 1/2 years old
   
she started drooling today sometime
   
she has not been eating like she used to
   
she has heavy breathing and is weak
   
we have gotten another cat reciently and he has picked on lately they are both spayed and nutered
   
she has been craving attention like never before and i am worried about her because she will not leave either me or my girlfriend alone
   

Your cat is very sick.
   
Any cat that refuses to eat could be in danger of dying.
   
Get the cat the the vet immediately!

yes my g/f is a vet tech so i had her take it to work she either has FIP or some immunemediated disease we are trying to get her fixed i love my kitty and hate to see her suffer
