We have recently moved house and some parts are still under construction/renovation. My 7 month old kitten has temporarily had to adjust to being confined in my room 24/7 as it is far too dangerous to let him out alone when I'm away (this will only last for another 2 weeks at most). He was good the first night or two but has progressively gotten antsy and gets frustrated when I leave the room. He has peed in my bed twice now, in my laundry hamper, on my rug, and on the floor. He still uses his box, just not all the time. He is perfectly healthy as far as I know, and eating fine. He doesn't get much stimulation when I'm away apart from watching birds outside the window, he isn't interested in regular toys. Every time he senses someone outside the door he tries to dig his way out and meows excessively and makes a dash when the door opens. He has also been super keen on his food (finishing it all at once, very quickly), way more than he used to when he would just take small bites and eat gradually. I read on a website that this kind of behaviour is due to boredom and he is trying to get my attention by urinating inappropriately. Is this true? How can I improve this? I'm worried he'll continue this behaviour when he gets free roam of the whole house.
