I can understand that. Both my cays, my avvi and another, we're usually very sweet but neither of them lasted much beyond 11. Bess, my avvi, started peeing on everything. After probably a year of vet visits, diet changes and trying to live with it, mom decided to bring her to the pound during their adoption day. That was a shock for me as I got home from spitting break during my junior year of college. Mags was about 10 and she was getting reclusive, annoying and a bit senile so we have her up too. It's sad that things turned out that way but they were starting to do permanent damage to our furniture and my favorite computer chair.
