Tomorrow is his first visit to the vet, I would like any suggestions on transporting him and his poop. Simmons is 13 inches long. I have a very small screen cage,perhaps you are familiar with a " Sun Sanctuary",it's only 20 inches tall by 14inches inches in a hexagonal shape,would that be ok to take him to the vet in? When I got it ,the idea was to use it to take him to our son's house if we had to evacuate due to fires or is it better to take him in a paper bag stapled shut at the top like he was in to bring him home? What's the best way to take poop for a fecal test? How old can it be and still be used? Sorry for the long winded questions, and thanks for any help.
