Couple more *thoughts*...

This work is "scheduled" for Monday...

I'd make it a point to talk to the Complex Manager - and point out that you have to also "schedule" the Cats' Day Out... Be certain that that the manager takes steps to make sure YOUR apartment work doesn't get RE-scheduled for some reason !

And while you're talking to him - might ask if it's possible to have your apartment work done on TUESDAY? Might make the Cat Boarding a lil cheaper and easier on you. SOME Cat Boarding places do not open to accept pets on Sundays!
