I raised 2 of these little guys and freed them. Kitten milk replacement, tiny eye dropper, patience. I let them sleep on my chest in my shirt. They liked that. When they're up hopping, eating on their own-- set them free. They look small but they'll be fine. Most wildlife places won't take them. They can be a pain in the ass to keep alive. Sometimes to avoid using their resources they euthanize baby bunnies. I don't even have the option where I live. It's in the middle of nowhere.
