This is a behavior/health question. My oldest cat, Katie, whom I've had since she was kitten, will soon be 12 years old. She's had regular visits to the vet and no major medical problems. I've noticed that she has started to slow down a little, but that's about it. She still loves to play and has become even more active since Peter, now eight months, came home, in Jan. They chase each other all over the place! I'm thrilled she is so healthy and active and hope to have many more years with her. Just wondering if there are any behavioral/physical changes I should be aware of as she gets older. Thanks!
