The cat's semi-old, I don't know for sure how old. When the cat tries to walk, he wobbles like a person does when he's past three-sheets-to-the-wind.

A friend thinks its something neurological or Alzheimers, but I have no clue.

Inb4 vet, the person's too poor to take to a vet to do a DNA test / blood test / etc.

And don't sugarcoat it. I've outlived 6 cats in my family.

Might be constipated

That simple?

Is there anything we could give the cat to see? caster oil for humans, ??? for cats?

it might not be affordable but it's probably the best way just to be sure :S

well, shit

cat eating and drinking right?

Only way to really tell is to take the cat to a vet. Wobbling is still pretty non-specific.

Maybe let them know ahead of time that a responsible person doesn't adopt or buy a pet without having the means to support them. That means being prepared for emergencies, too.

here they have some vets that are free. maybe look into that
