It's official,,he has full blown senility. He no longer goes potty in the box and is incontinent. He will however go on the puppy pads we put down in an area he goes in freq. He continues to eat good. He still howls at night and at the walls sometimes. He does groom himself still,,kinda so we have to help him sometimes. He sleeps most of the time but will have bursts of energy and become very playful. He does bite more,,,nip more when petted. He has trouble going up and down the stairs and takes them one at a time. He hisses at the other cats a lot as well. I am going to discuss some pain medications with the vet for the arthritis and general degenerations that occur with aging. It makes me sad to think that he doesnt have too much longer with us. The first sign that signals he is declining or suffering I will have him put down,,,he seems content most of the time. Yesterday he was eating his dry cat food like potatoe chips,,he's stick his paw in the bowl and pull one out and eat off his paw. He also is eating whatever he finds that is left on the floor,,he ate my daughters barbie shoes and chews up pictures. We got doggie stairs for him so he can get in bed with us,,he sleeps right next to me on the pillow. Any other comfort suggestions??
