My squirrel is about 4 months old. Today he was fine but around 2 hours ago I found him clinging on the edge of his cage not moving but breathing very heavy. I thought he had gotten to hot so I reach in and grabbed him. He usually resists but this time just went limp.
He is still very limp and only moves when absolutely has to. He won't eat and I think he is peeing blood. There is a lot of blood where he was laying.
He drinks from a water bottle hanging from the side of his cage and he only eats peanuts. This has been his diet for 4 months.
He makes a piping sound when breathing but it doesn't persist all the time.
