I found this squirrel in my back yard with paralyzed back legs so i put him back on the tree and he climbed up but the next day i found him on the ground again, i’ve been taking care of him in a box with towels, crushed nuts and cashews, acorns, apple juice, almond milk, water, and ibproufen mixed into water, i’ve been feeding him through a syringe, and he is eating acorns on his own and cracking them open, but his back legs don’t seem to be getting any better, i have contacted multiple wildlife associations and none have responded, please help. I’m located in Lakeland, Florida
