Need help, caught unknown lizard!!

Provided you can offer your lizard the correct care (once it's species is deifinitely confirmed) then I don't see why you shouldn't keep him/her. Did you see a specialist herp vet to try to determine the species and for your lizard to have ageneral health check to make sure it is healthy? Also, I think you should call it Hobo - a little wandering lizard waiting to be found lolol Seriously though, good luck with raising it and finding it's exact origin
