What I’ve remembered about young cats since Inky came to live in my house:
Watch where I walk, because he will be right underfoot, risking mashed toes (his, not mine).
Watch which doors are open, so he won’t get caught inside a room or, heaven forfend, outside.
For the same reason, don’t open windows any further than the width of his head.
Don’t let anything drop to the floor–food, string, Q-tips. This holds especially for things you might want later, like pens, paper clips, or the little thingies you put in electric sockets to avert accidents. Let things like that drop to the floor, or leave them on a table, and they are just gone.
Don’t leave your laptop sitting anywhere with the lid up. Same goes for toilets.
Young cats like to climb on high objects: bookcases, DVD cases, kitchen cabinets, armoires, pot shelves.
Young cats, in fact, like to climb everywhere. Like behind my pedestal teevee, which scares the crap out of me.
Speaking of crap, young cats dump a lot, and often. Eww.
Young cats need to be shut in a room or a closet when food is being prepared–mine or his.
Young cats don’t just play with toys–they emasculate toys. And they don’t do this quietly, particularly in the middle of the night.
