I have two cats and my current vet lets me schedule an appt to bring them both in at the same time for their annual examinations and shots. Can I do the same thing here, or is it only one pet at a time?

I have done that with our ferrets on more than one occasion.

You can schedule both of your cats at the same time.

I have done that with puppies, don't see a reason why not with cats.

Unsure. However they are still open and someone will definitely let you know if you give them a ring.
