One of mine gets a long walk every evening and she fusses at me and my husband until we take her out after dinner.
The other is old, arthritic, and can barely stagger into the back yard to do his business before coming back inside despite being on several meds, but his appetite is still good and he hasn't told us that it's quite his time yet. We could try to walk him but I don't think he'd make it past the mailbox.
