Bastian's Medical Costs

The kitty on the left is Bastian. I rescued him literally three years ago after he was apparently abandoned in my neighborhood. He's a sweet boy and my middle fur-child.
But he's having a problem with one tooth, I'm unemployed with no income and a dwindling bank account.

I currently can't even afford to take him to his vet to see what needs to be done.

The amount I'm asking is currently an estimate - I'll update once I have enough for the vet visit.

Thanks for any help you can give.
