It is finally warm enough for my almost year old Hermann's tortoise to be able to spend some time outside. I have a section of the yard that I cleared of weeds that I was unsure about, but apparently I missed some small pebbles. (The permanent outdoor enclosure is in the works.) I picked up Little A'Tuin & tried to get a grip on the little stone, but he was determined to hold onto it, and he swallowed it. Should I take him to the vet? Should I wait to see if it will "pass"? It looked like it was big enough to be painful if he has to pass it. Any advice would be appreciated.
