I have a legitimate prescription for my pet bird, from a licensed avian veterinarian, and the clowns at VetRxDirect refused to fill it because it is off label. That simply means my pet bird needs to take a medicine that is formally approved for dogs and cats. Guess what... this is extremely common in veterinary medicine! Pet birds are prescribed 'dog and cat' pills all the time. I marched my $220.00 order right on over to another site, which happily filled it after confirming the details with my vet. Don't waste your time on VetRxDirect, they're not worth it.
