Sire 1.5 years old and two siblings 1 year old
Only 1 sibling developed warts. Why?
"Did the father bully him only?" I asked.
"Yes," the young man said.
"What does the hamster do?"
"He lies flat exposing his tummy.
Electro-surgery to remove warts in right front legs (paws, pad, elbow area. No bleeding. Hamster recovered and went home. This may be one case where warts develop due to stress of being bullied by the sire. Left fore develops small wart that is too small to remove. Hard to prove my hypothesis.
Advised: Put this sibling in another cage.
