Kitten advice needed

Google lots. LOL, I did not have that option when I got my first one, then two.....................

Litter box. Lots of options, mine did well with the grocery store "non wood" stuff, they almost self train. Just stick them in the box a couple of times. I don't think all 3 of mine over the years had more than a couple of "accidents."

Depending on your windows, I would open one with a heavy screen above my bed, they loved to jump up and lay on that sill in summer, and I screwed a shelf to the big window in front with carpet and when they were older, put a ramp up to it. They LOVED that it's E and S exposure lots of time lounging in the sun.

I kept mine pretty much indoors, I think Rusty is the opposite

Please DO NOT declaw cats. Teach them to use "designated" spots. Buy scratch devices, maybe one of the carpeted tower/ castle things or build one. If you keep at it they will get the message. If you are home a lot that helps. Teach them "NO" and what it means. Mine all learned where they could climb and where not. I had little trouble with them say, on kitchen counters.

I miss all of them.
