So my brother was holding the guinea pig (Butter, male around 9 months old) at around a 2ft height, and Butter decided to jump onto the carpet and ended up getting hurt. After observing a few minutes, Butter was able to walk pretty normally but he was favoring his back left foot over his right foot. After 30 mins passed by I saw that on his right foot the outer toe had swelled up; I got pretty worried so I decided to gently touch his right leg to make sure there was no swelling and thankfully there was none. I put him back into his cage to rest and calm down, is there anything else I should do for him.
