employment causes abandonment issues

Banik has been a stay-at-home dad ever since we got the kittens. Sure we do stuff on weekends or evenings, and he had evening classes for a while- but he was always home all day.
But he's been gone all day. And now all they're doing is watching the window and running around looking for him.

They're probably blaming me for this. When he's not here and I come home without him, the cats act like I forgot him some place. Apparently I'm careless with their human.
