I'm sure the weather is the same in a lot of places as it is here in Cleveland-hot and humid. In the past few days, Ivo has been less active, spending a lot of time sprawled out on the floors (wood or linoleum) than sitting in her kitty condo. She also has become less active. Her appetite is still good, she's drinking water, and using her litter box normally. I'm sure her behavior is normal, given the weather, but when should I become concerned?
