Here are my two cats Echo and Jellybean
The are house cats with supervised leashed walks. I believe this keeps them healthy by giving them the advantage of not being in danger of vehicles, animals, or diseases etc, while giving them the exercise they love.
They are rescues, Jellybean (male) is two years old and Echo (female) is a one year old.
