You have to carry your pets.
Don't remember any sign but keep in mind isles are very narrow and crowded. Breakable merchandise throughout the store, pets would NOT be advisable.
Yes, there is a sign that says you have to carry your pet while inside the venue. So if you have an elephant as a pet...it has to be small enough to be carried in your arms.
I believe the sign said that you had to carry them.
