My kitty is 14 yrs old, too. How long did she do that before she died?
Motorola only stared at the wall for a couple (2/3) days and I can’t remember now if I took her and had her put to sleep or she died here at home. I am thinking she died here at home. I remember I took her food and water to her at the place she chose but she wouldn’t even look at it. I am sad for your kitty (and you).
