The common reasons a tortoise won’t open its eyes are vitamin A deficiencies, post-hibernation anorexia, third eyelid problems, trapped plant matter, infection of the eyelids, and an abscess. Some tortoises have a tendency to keep their eyes closed longer than normal so if your veterinarian rules out all issues, it’s nothing to worry about.
Pet tortoises should have access to clean, fresh drinking water at all times so that they drink whenever they want. Tortoises also drink and get hydrated from their regular soaks and by absorbing water from their food. A proper diet, access to fresh water in a shallow dish, and regular soaks ensure that your tortoise gets enough to drink.
There are 3 main reasons for a tortoise that keeps pacing: It’s a normal mating behavior designed to attract the opposite sex, it’s a reaction to the glass in some vivariums or terrariums, and finally, it may be that your tortoise is from a species that walks a lot and finds the enclosure a little small.
