Vets in auburn alabama:
There aren't many in town that know alot about rats and small animals. The one I recomened is All creatures vetinary clinic on 2050 Wire rd auburn alabama. This is the vet we use for rats and any sort of exotic pet for cats and dogs, and if we can't get hold of the rodent expert we go to the opelika vet clinic. Brandon been taking his dogs to Doctor Colley since he was 10 so he trusts them.
short comment the one time I dearly neaded a mouse vet everyone that knew anything about rodents decided to go on vaction. Took forever to find one. So I recomend trying to learn about rodent first aid in case this happens to you.
