My cat Rusty, rest his soul....he was getting old and had a hard time climbing on the couch or my bed. He had his claws, the others didn't. He was smart and didn't try to destroy the furniture.
Anyway...I bought a thick towel that went on the couch in HIS spot. He could get his claws into it and get up that way. Plus, he didn't ruin the couch. I also bought him a step stool so he could get up on the bed. Hubby thought I was nuts. Rusty is now gone, he was 18 1/2.
We still have the stool. Guess what hubby calls the stool? Yup....Rusty's stool! lol
