Hi my 7 month old kitten started grooming himself very aggressively. He has an almost bald spot on the side of his tail, there is still some hair there but I can see the skin. I have also noticed him bitting when he is grooming himself in that spot and on his stomach as well (no bald spot on stomach. I’m wondering if this is something I should be concerned about, and if I can do something at home to help with it.
