Our two cats like to do this with the back of the sofa, or, by the patio door!
We have one who the wife calls her "dumpling" who is quite ... tubby ... then, other one is old and skinny since she can't seem to keep down anything she eats (after 2 years of trying every different food and working with the vet, she's more or less on a wet food only diet and maybe starting to regain some weight.)
The place sounds awesome , I'd sacrifice half of my square footage in a heartbeat to be waterfront/at the beach.
