Talk to me about kitten proofing. How much covering of wires and cables do people actually do? What do you use?
The main thing for me would be making sure that there are no plastic bags accessible as they can be a suffocation or choking or intestinal blockage risk and a lot of cats (especially kittens) for some reason LOVE to chew plastic bags - so anything that you store in that sort of flimsy plastic, make sure it is not accessible, in a cubpoard or something.
Kittens are a bit like puppies in that they like to explore things with their mouths so be aware of things like small jewellery items - get into the habit of putting them somewhere safe in a drawer or a jewellery box etc. if you normally leave them out somewhere - same for small trinkets or ornaments, just be aware that everything is going to be viewed as a toy and could get pushed off a shelf or hunted
Strings can be a big hazard, if a cat starts to swallow something they are actually physically incapable of spitting it back out (due in part to the backwards barbs on their tongue) and anything string-like that goes in could cause intestinal damage/torsion, so have a think about if you have throws or shawls with tassels - you might want to store them in a cupboard or wardrobe while the kitten is little, at very least so that they don't get wrecked when the kitten inevitably decides to play with and attack the dangly stuff!! I would say the same about if you have any old blankets or tatty towels with threads hanging off, just give those threads a trim - although every time I have met you you have been very well turned out and glamorous so I'm struggling to actually imagine you having anything that is really tatty, but I mention it just in case
Along similar lines, tinsel and stuff like foil strands is absolutely devastating in terms of internal damage if ingested, so if you have xmas decorations make sure they are out of reach, including when you put them up.
Make sure any and all medications are completely inaccessible. Same goes for cleaning products and laundry chemicals/dryer sheets. Also that any lotions and potions have caps/lids etc.
Some kittens do chew cables, but definitely not all - my Radar was a real fiend for it but neither Sonic nor Jakey did. The main safety thing is to make sure there are no loops of cable where they could get caught up and hang themselves, they do like to wriggle behind stuff. If chewing is an issue, you can get a product called "Bitter Apple Spray" which is non-toxic but tastes utterly foul - you can spray that on a cloth and wipe down cables with it if cable chewing is an issue and it is a good deterrent.
One other thing to be aware of is stuff that is propped up and could fall over. They do like to climb up stuff and charge around - I had a large mirror propped against the wall, very heavy frame on it too, Radar knocked it over on top of himself when he was a kitten, my heart utterly stopped when I investigated the crash and saw just a little white paw sticking out from underneath it - I do not know how he didn't kill himself. A friend knew of someone who propped up their heavy chopping board/block, a kitten knocked it over and unfortunately died.
Always, Always check the washing machine/dryer before starting them - this is a real hazard for cats of any age and I have heard several awful stories of cats going in there for a snooze and not being noticed and yes it does not end well. Same with fridge and freezer - again these are things I have heard of happening, I know of someone who had a kitten get into the freezer and they shut it in - it did survive, but lost both its ears to frostbite.
If you have a reclining chair always check where the cat is before reclining it! And watch where you sit!
Oh and those protecive plastic covers for unused electrical sockets are a good idea too. (My Jakey quite recently nearly caused a fire by vomming into a socket on an extension cable).
It's been a long time since I had kittens, all this may sound a bit alarmist, but they are all things that I know have happened to other people and their kittens, or that I have personally witnessed, so just some stuff to take into consideration and watch out for.
EDIT: Oh if you decide your kitten will wear a collar, start early so they get used to it - but make sure you use a breakaway safety collar - these have a weak bit that will break if much weight is put on it - so the cat cannot get caught up and hang itself.
