I have a little two year old hedgehog named Zed who's been fighting an infection in his spleen. Yesterday he climbed the outside of his cage and fell. I rushed him to the vet, she checked him out and he looked okay. I'm worried he fell and injured his enlarged spleen. The doctor said to watch him but I'm not sure what I'm looking for. He's very sleepy and cries until I hold him in my lap. He's eating okay and he was running on his wheel last night. What signs should I be looking for and for how long is his risk of internal bleeding?
