We went to the Greenfield Veterinary Hospital to get a travel health certificate for our cat. They were very prompt (and we were very lucky) so we got scheduled within one hour of the call. The cat had to get some vaccines and we payed a lump sum but we liked how things moved smoothly. Furthermore, the staff handled our scared cat very gently and there were no meows to be heard so all in all a good experience :)
Shame we're moving out of Pittsburgh and wont get to come back to this place.
