LOL! I meant their outer thighs, not clogged anal glands.
Nah, you’ll learn their favorite places for scratching. Once they grow thick adult fur on their hindquarters, it’s harder for them to scratch. You’ll see them walk by a sofa, or the arm of a sofa if it projects out, and then do the bump against it or your knee (once you’re properly trained to scratch over their tails, of course).
We've scratched them so much I had to make the kids leave them alone before their fur was rubbed off. We'll all start anew in the morning.
They have taken up with my grey love seat and it's an adorable sight. I must remember to get them doggie beds tomorrow. I bet they won't use them though.
