I know from my security camera systems that my cats spend most of the time when I'm away sleeping. Within a half hour of me leaving the house, they are off napping somewhere. On a regular office work day for me this means that they are sleeping from 8:30 to 4:00. If I'm gone traveling, they sleep all day and all night, waking up only to eat, drink, or go to the bathroom. Occasionally they'll saunter out to the catio or look out the window, but it's mostly sleeping.
And now that I'm home a lot more than usual?
They are awake a lot more than usual. Sure, they still sleep for hours at a time... but they want to sleep near me while I work or play video games or watch television. This can cause a problem for Jake, because he tends to blend into the background. Especially the fuzzy blanket I got at a Christmas gift exchange which I leave on the couch...
He loves that thing. But, as you can imagine, I've come close to sitting on him more than once. I've have to really remember to make sure he's not dozing away if I'm going to sit on that blanket.
See where his head is? Take your time, because it's not where you think it would be. That's how he sleeps. I have no idea how or why, but that's how he does it.
As you can imagine, spending more time awake is more opportunity for conflict... even if it's play conflict. The other day I was watching Jenny giving herself a sun-bath out in the catio. Jake decided he wanted to sit where she was sitting, and took a swat at her. Now, most times, Jenny will decide it's not worth the trouble and wander away so Jake can have his way. But lately? She is not having it...
Jenny may only be 2/3 the size of Jake, but she can and does hold her own when she feels like it.
Lately for me, "holding her own" means demanding belly rubs whenever it occurs to her that she wants one...
Seriously, she will meow and fret until you give in.
I always give in.
