Looking for advice from all you wise cat people. atm I'm home full-time so she's in and out, in and out, in and out.... I have to open/close the door (no cat flap or open window) We are going away for 2 days/1 overnight and NDN has agreed to come in, feed her and stay with her a bit, check on her and the house. This is the first time we've left her. I was thinking of reintroducing the litter tray so she wouldn't have to go outdoors and give my NDN extra worry about looking for her and maybe not find her. She had stopped using the tray herself a long time ago. Should we introduce the tray a week beforehand? Will this all confuse her for when we return and remove the litter tray? She's 2. TIA
