Wanted to ask a question in regards to a rabbits hair affecting prayers. For cats they say a maximum of 3 hair and for a rabbit I read from another sheikh on this website saying it will not invalidate the prayers if the furs are not too much on the clothes, but what could too much mean ? Because when we hold the rabbit it gives hair on our clothes and we try to wipe off what we can.

The marja’ saying not too much would be in the definition of common usage of people as what is seen as not too much.
Scholars differ on this even with cats. Some say a few hairs are ok whereas others say none. The usage of three is just to denote a small amount
