Help Heal Frankie's Broken Leg

Hi all, I found this stray cat on my block that had been a stray for awhile now, my neighbor took him in and is caring for him because I just had a baby. My neighbor and I am in no position to fix this kitty’s leg, he seems to have one broken hind leg. I took him recently to a low cost vet who will cover the costs of a visit, x rays, medications and surgery. Please if you have anything to spare for Frankie the cat, we so appreciate it as we want him out of pain and able to walk normally. Thank you!
