I have a domestic long hair cat, she is part Persian I am wondering does cat fur grow back and would it be right to get her trimmed, or even her bum area shaved cause she always has dags? I also have a short hair cat who has very thick fur would it right to get her fur thinned out, I know I should brush them but it takes a long time when they get sick of a brush after 2 mins I love my girls but I would like if I can get there fur trimmed so there lower maintenance and my clothes won't get covered in cat fur every time I pat them, they literally malt a lot of fur constantly not enough to be a health concern but enough that My clothes are covered in cat fur every time I leave the house unless I spend 30mins using a lint roller please advice and oppions
