I have a California desert tortoise, name Otis who is 14 yrs old. I just found out via a vet visit today, that Otis is actually a girl. I took her in because she became somewhat lethargic over the last two days. The vet seems to think she was dehydrated, and he gave her a huge injection of fluid with calcium, however her mood/energy has not changed. Has anyone experienced this before.... Any suggestions?
