It's been a week with the kitten and my sleep hasn't really suffered considering he sleeps with me half the night. I've woken up a few times from him climbing on me but he's pretty behaved about learning when the giant bipedal furless cat is asleep and won't be getting up (very different from a dog's needs). 

Have significantly reduced my edible consumption in order to not be tired just in case. Very easy sacrifice. 

More than once I've put off training to tend to him or just catch up on chores, and since I'm not losing weight I think it's only benefitted my strength. Boxing and Muay Thai training at home have been greatly reduced lately although I've gotten some shadowboxing sessions in, will greatly increase that. I've gotten sidetracked about going to the gym and need to work that out, too.
