Young cat and window safety

[tangledyarn]

It's coming up to summer (hopefully) and I'm just wondering what to do about my upstairs windows. Is little cat (9 months) likely to throw herself out of the windows chasing birds and is so do I need to get some kind of screen or netting? Or to cats tend to realise that it's too high and just go out the back door?
Thanks

Mine jumped/climbed out of the upstairs window, luckily I have a small pitched roof over the front door and he ended up on that.

Lots of fun ensued with me leaning out of the window and standing underneath with step ladders at 1:00am to get him off the roof. Hopefully all the neighbours were asleep

Now I only open it a crack, not wide enough for him to fit through.

Mine haven't fallen out, I'm on the first floor, but they're a touch older so maybe a touch more sensible.

There was once an incident when an unexpected dog appeared in the living room, which led to the madcat somehow scaling the glass to perch on the top of the open windowframe, howling and wobbling. Stiff drink required after that one.

I'm very pfb and she is truly the light of my light despite being a bitey little thing so I might be overthinking it. Also my parents kitten came to stay and fell/jumped out of the window but she wasn't allowed outside and was very eager. The netting solutions look either ineffective or very expensive and as I'm in a rented house I'm not keen on spending loads.

If you have a cat flap, so your cat always has an easier way to get out, and as long as the windows aren't the tilt and turn type which are extremely dangerous, then I don't think you need to worry.

I don't have a cat flap but the window would only be open when I was in in the daytime in the summer and I'm just tending to leave the patio door open constantly because she's demanded it be that way
Might just start opening it a crack under supervision and take it from there..thanks guys

My 11 year old cat, as a kitten, did jump out of a first floor window

There's a product called flat cats which covers windows with a mesh which can be moved around to different windows of the same size. May be worth looking in to for peace of mind.

Many moons ago DCat was staying with my parents in their flat that was half way between first and second floor (Edwardian house conversion). They mislaid him and found scratches on a slate bay window roof below an open window - he was finally found, somewhat dazed and scared, 2 floors down in the garden. He was a bit adventurous though - on another occasion was found up the chimney having caused a soot fall.

My rescue cat (about 1 year old at the time) decided to jump out of dd's bedroom window twice when we first got her, but now had her 4 years and she hasnt done it since. Nowadays she just sits by the back door crying to go out, then wants to come back in again

I've lost a cat through a head injury (killed instantly) through a 3rd floor window. She was a fearless adventurer though.

I use Flat Cats on upstairs windows. They're brilliant, they stick on with velcro, so no damage to make good when you move out. They withstand Little Monsieur launching himself at them and hanging on with his claws, in order to make passers by think he's one of those Garfield car window thingies. So definitely strong enough.
