Trap and treated a stray a few years ago. Took him to vet and was told FIV+.

Kept him and he is doing fine.

Vet said that FIV+ sign is seen by looking in mouth at his gums.

He gets coconut oil every couple of days.

Wormwood, but not much, can be dangerous.

Colloidal Silver in water.

Why not check out animal rescue place, they have coupons for discounted vet services.
