Hi this is my first time on here.and new to owning a tortoise. I have a horse field tortoise about 20 month. I have a UV light and a basking heat lamp. Temperature at a steady 35. Lately my shelby(tortoise) is a little lethargic not eating much. Can she be trying to hybernate. Shelby has clean water changed during the day she is going to see the vet on the 21st for a check up or should I take her early. Any advice please thank you Joe and Shelby xx
