I'm prolly going to be jumped for saying this, but if you aren't willing to take on the expense and commitment of her treatment - then she'd probably be better off put to sleep. She can't continue to suffer. Another option would be to contact your local pound and see if they have anyone that would be willing to take her on and give her the treatment she needs.

I'm not a huge animal lover (God bless those of you who are!) so I can understand the hesitancy to take on this treatment. If you do put her to sleep, don't get another pet unless you are willing to do the annual vet visits and keep them healthy. It's sad enough when they are strays and sickly, but it's really horrible when they are pets and neglected.
