A portion of basic supplies such as litter or flea-treatment

Roughly the cost of one basic vaccine dose (vaccines run ~$20–30) or help toward deworming / parasite prevention for one cat.

A significant contribution toward vet care — e.g. vaccines + deworming + flea treatment + partial spay/neuter costs.

Might fully cover a basic spay/neuter surgery at a low-cost clinic, plus initial medical care (vaccines, deworming) for one cat — major step toward making the cat “adoptable.”

Enough to cover all basic rescue costs for a healthy cat: vet care (fix, vaccines, deworm, flea, microchip), and food, litter, basic supplies — effectively “rescuing” one cat from intake to adoption.
