When I have taken reptiles in from Petcos adoption table. I take extra precautions.

I usually do a 90 day quarantine, plus a vet check. Luckily I haven't had to give any meds for anything yet, but if I were required to do so, I would complete that then do another quarantine to make sure things cleared up.

I keep them in a completely differen't area of the house than any other animals.

Once I know for 100% sure they are healthy I will look for a home.

I don't do this on a regular basis though, just occasionaly when I see a herp in need of help. So I wouldn't call it a rescue, just a favor to the little guys
