A few months ago, we began noticing subtle changes in one of our cats, Paul Revere. The litter box started seeming more full than normal. Paul was sipping from the water dish more often than usual. When we returned from an out-of-state trip in July, he seemed to have lost weight.
Initially, we assumed our 9-year-old kitty was simply showing signs of his age. But when he began leaving puddles around the litter box and walking with an uncomfortably arched back, we called the vet.
