PSA for people putting in stairs for aging or smaller pets so they don't get hurt trying to jump up too high. Our cats had no clue what the stairs were for. Especially the 3 legged guy who was the primary reason we bought them. Until we took them and carried them up the stairs placing their feet on each step. Did it a few times and suddenly it figured it out. Now we can't get rid of him at night.
So a little training might be required for the stairs to work. Not sure how I'd do that if I had a 70 point pet.
