My cats tongue is very swollen but only at the tip, the rest of the tongue seems to be fine but is whiteish, she can't eat or drink so I have been giving her small amounts of water with a medicine dropper and I can't afford a vet, help me please!! :(

You, as a pet owner, must find a way to get your cat to the vet. Call your vet and ask for a payment plan. It may be something very minor, but could lead to death without vet care. Please find a way.
