Natalka I am sorry for you loss of your kitty.
Our cats are 10.5yrs and 11.5yrs Old. We adopted them from our local humane society when they were about 10 months old. King is the older one and has been having some trouble the last few months, we’re still trying to figure out the cause. Some of his behaviour has changed, but he seems otherwise happy and healthy. Elvis is a little chunky, but acts younger than his years.
