Kimbabear has experience. Kimba had a hematoma after his neuter and they ended up removing the sac.
Kimba's hematoma was HUGE.
Blu went thought this in May. His problem was he had a retained testicle and it was still in his belly that is were he started licking. I did hot packs on it and after 3 days it was gone. Blu's was also hot so he was put on cephaxine 3 times a day. Blu knew I was helping him and all I had to say was fall down and he would lay down with his feet up Hematoma's will go away just make sure it's not warm.
