New England Wildlife Center’s Odd Pet Vet treats many unusual pets – from service pigs to tarantulas. All fees support NEWC. OPV provides veterinary care 7 days a week and we offer boarding services. Below are two frequent visitors to OPV -chickens and iguanas. Dr. Mertz captured two of his favorite animals living in the wild on a beach in USVI today. It may look like a cordial visit, but food was between them. In the end, the iguana ended the stand off and made off with the snack.
