Re: adult gray found with broken arm
My vet can gas this baby so it is an unkowing participapant in treatment. Arm will most likley not be reset, but bandaged with a splint to heal. Then the squirrel will need to be kept where it cannot climb, like in an aquarium. I have one you can use.
However, and adult wild squirrel is not likely to leave the bandage alone, so I'm not sure it's worth putting him through that.
Can you get a picture of the arm?
