I recently moved in with long time family friend and her husband. The living situation is awesome, we have a similar level of cleanliness, and I have a very low rent payment. Although I am far from rich, I do get a monthly bonus through my job that totals around $100 that I usually use to go to a local concert or treat myself to a nice dinner.

My only issue is my roommates have three cats, and one of their cats has a medium length coat that is very matted and seems to be causing her some pain. It is beyond the point it can be brushed out, or I would just do that. Would it be rude to offer to help pay for a groomer or vet to get the cat more comfortable? I'm worried my roommate would find it offensive or take it as a personal slight.
