In Winter it gets darker quicker (this is in England but this advice can work any time in the year) the most important thing is NEVER let your cat out at dark, 5-7pm or am, as these are rush hours where cars are eather going to school or work or coming home. This makes people rush and increese them going a bit over the speed limit which could easily lead to drivers who are not watching the road and they won't have time to stop for your pet. Make sure you can at least see the road from your window (depending on where you live) also test how good your cats eyes are in the dark. You can do this by turning off the lights and throwing a treat (this sounds strange but will make sence) try running at them with a bright light (this is so they don't freak out over headlights) or just play with a toy in the dark.
Here's a good Youtube video idea but cats climbing trees are definitely a problem especially kittens, who could break an object or hurt themselves. The best thing you could do to stop kittens and cats from climbing a tree is buying a fake one. Don't use cat repelent as thats just mean and might even stop them from climbing trees outside. If you have a fake tree and your cat still climbs it you need to just let them (I know it sounds stupid) but they are only climbing the tree out of curiosity. Let me put you in a scenario (thats much like what the cat would be in) ok so, your walking by in your town and your see two MASSIVE doors but there locked and day after day you see your best friends open that door but you never see whats inside. Now imagine one day you see that all the guards are on lunch break and the door is left open. I bet the majority of you would look to see what all the fuss is about. That's what a cat goes though seeing us use the tree to store present's under it, but every time a cat try's to climb it they can't because the door are locked. Right just need to finish this story. You enter and you realise its just a balcony nothing special you go to leave but the guards have all surrounded you and you can't escape meaning they have to take you to jail. Punished for being curious. Ahhh... the story is comeplete. This is probably a very strange thing, that you never even thought of, IF you let your pet (cat) climb up that tree they won't do it again beacuse its just a balcony. Nothing that speacial.
I MIGHT do questions 3 and 4 but i'm not sure, you could tell me or not I don't really mind, hey it's your time.
Thanks for reading this I just want to make sure your cats or kittens are safe.
