Hes a Russian Tortoise and it will be only 3 days but i didnt know if it will hurt him. Hes 4-5 inches and if its not fine should i leave food in the cage or feed him alot before i leave? Thanks!
Buy a head of escrole and leave it in with him. Escrole lasts better than other leaf stuff. 3 days with that, and he will be fine. I would not even think twice, regardless of the torts size.
He will be fine. When I go away I will take my hatchlings with me, but my adult tortoises stay home and they are just fine. Throw down some extra greens (as mentioned above, "heads" last longer than cut greens) and don't worry about it.
