This question is a little bit difficult, because it really depends on the size of the animal, the temperament of the pet, and other factors. You probably know the answer to this best. Our biggest concern our claws and teeth. Those sharp little claws on say, a cat can really do damage to the canvas. A well tempered animal would do just fine in the tent provided they don't jump around and claw on the screen windows. Having said that, many of our customers bring along rambunctious animals and keep them in a pet porter or have them supervised (night time) to make sure nothing is compromised.
