FIP is horrible.

Hi my name is Rita. I have rescued cats for years and always used my own funds to pay for vet visits, meds, foods etc. I'm asking for help now for this kitty named Tucker. He's a foster fail and is now 4 years old and the vets are pretty sure he has FIP. I can't afford the lifesaving treatment for this horrible disease and I'm reaching out for help. Please help if you can, he was bottle fed as a baby because he lost his mama, we love him so much and will be heart broken if we lose him.
