I see people feeding cactus leaves to their torts. Can Russians eat that as well and if so is this the right one?
And don't be surprised if your tortoise doesn't want to eat it right away. Tortoises eat what they've eaten before, so it might take some time for you to get him to eat it if he hasn't seen it before. Cut up a small amount into tiny little pieces and mix it in with other favorite greens. This will get him used to the smell, taste and texture. Gradually, add more of the opunita, and eventually you can just drop half a pad in there.
And the spines won't hurt your tortoise. They just hurt our fragile human hands. I've been feeding whole pads, spines and all, to all ages and all of my species for years with no issues. In the wild they eat fully spined cactus pads with no problem. Even species from countries like Madagascar where cactus doesn't occur naturally. I've seen footage of wild radiata eating introduced fully spined cactus. Farmers there use it to encircle their fields to keep wildlife out. The tortoises just walk up and eat it. I don't know how those spines don't affect them, but they don't.
Now that I think about it… When I'm walking around the ranch doing tortoise chores and I get those spines stuck in my hand or arm, I pull them out with my teeth and spit them out, and the spines have never stuck in my mouth. Hmmmm...
I tried out the cactus leaf and my little male devoured his like someone was gonna take it from him. My female who normally is my piggy and will eat anything from my hand before I can even set it down for her was pretty indifferent to it.
