MrCat is getting older and stiffer (as are we all) and doesn't groom the base of his tail any more. I think he's also missing out the rear fringes of his 'pantaloons', as they seem a bit knotty.
Fortunately MrCat is amenable to bring groomed. But it pulls a lot of fur out, especially from his tail and rear end, so I don't want to over groom him.
How often should I comb or brush MrCat?
