My tortie was climbing trees at this age, but for some reason not a master of climbing down. After several incidents of her calling to me from the rooftop in the middle of the night, I made the decision for her to be an indoor cat.
She lived to be 18, and it really was sad to see her when arthritis set in. I even built her a staircase out of boxes so she could get on the bed.
Get your climb on, Lalah, before you get old!
