We live together with a cat in a flat in the second floor (one above the ground). She has been an indoor cat all the time so far. When she was at my girlfriend's parent's house she could have gone outside, but did not want to.
Now in the flat, she tries to get onto the balcony when I am doing laundry or so. Once I am back in, she will sit in front of the glass balcony door and meow. I have the impression that she wants to go out. A couple of weeks ago, she started to go onto the balcony, and we watched her. She just sat under the dryer and looked around. A couple of days ago she slipped through the railing onto the neighbor's balcony and went a bit into their flat. Today, I was putting up clothes and she darted from the flat onto the balcony and through the railing. Luckily, the other door was closed, but it took a while until she came back.
My girlfriend is very worried that she might harm herself somewhere, and we are not really sure how the cat would get outside and inside from the second floor anyway. The ground is just some 2.50 meters down, so I guess she could get up with some sort of rope or ladder if she really wanted. We live rather close to the city, so there are some larger roads in reach.
She often wakes up from dozing in another room and meows continuously until she is in the other room and I pet her a bit. Often, she will come close to me and meow in a demanding tone, then behave like “pet me, but don't touch me!”. I do think that she might feel a little bored since there are no other cats around and she does not care for any toys, except a laser pointer which I do not want to use.
Would you think that it would be good for her to go outside on her own or on a leash? Or would that confuse her in a way that would be negative overall?
