My cat in the past never saw the streets, so he took every chance to escape. He was so energetic/playful/hyperactive inside.

This new cat, she is young but rescued from street, she is little bit more easygoing and doesnt attack yuu when you pet her.

They both stayed alone in a 7m² balcony and we let them roam in my room when we are not at work.

I think they shouldnt be staying inside a house at all, they need to run and climb trees. The 1st cat I mentioned now live with my relatives who have a private garden, I am guessing he is much more happy now. Because he was not an indoor cat.

We rescued this cat for temporarily, until her scar is healed and we are planning to release where she was found. Do you think a room that small inhumane for a cat or street is worse.
