I got a kitten for my partner, 9 weeks old, lovely. After we got home, i stayed up for an hour and went to bed, dp staying up to monitor him and pfc together. I expected to be up when he was getting to bed, but he went to bed way earlier than i expected, and when i got up for a midnight wee, found the kitten in the carrier. I went and got a mesh dog crate from under the bed and set the kitten up in it with a bed, tray and food/water. I stayed calm and tried to wake him up and tell him how it's absolutely unacceptable to leave a kitten that young for potentially 5 hours without food or water, or a litter tray, especially unmonitored? He loves the cat and is great with pfc, and has been very excited about having his own, as pfc was an adult when they met. He's researched loads about kittens, I just think it was a ridiculous oversight. He knew where the crate was, just didn't think of it.
Aibu to be seething inside, over what i think is essentially him having a huge oversight? If id have not got up, he would have been in there for 4 hours longer until my alarm went off. And would have felt awful for the kitten, and even more furious.
Simple mistake, but awful potential consequences :(
