Ok I am new with cats this is my first time having a cat and I kniw that they shed a lot but my cat seems to lose hair way too much and especially on her back. My husband pulled some hair and now there is a small bald spot in her shoulderblade. Plus we noticed that her hair on her back fall a lot even if you pull them gently. Is this something to worry about? Or is it shedding season. I have the cat for only 3 days. Cpuld it be stress?
