start your point of accountability with your cats at home and expand on it. small steps first. if they are what makes you feel alive again, maybe add in a scheduled playtime, or grooming them, things that might motivate you to take care of them more. Then add in what do i need to do for myself in order to do this activity with your cats.
suggested steps:
need to eat something before activity with cats.
need to get dressed....
need to get out of bed...
need to brush teeth... they might not like stinky human breath (lol)
I had a similar list to what is above when i started volunteering at the shelter. i used my own cats at first. they took care of me, what could i do for them to show how much i appreciated them being there in my worst days. and i kept expanding on it small step by small step.
this acountability is easiest to start with, animals are very forgiving on schedules. no pressure.
