I did get the fountain working - extension cord and a "normal" power outlet.

Oscar likes the dry urinary food but Zoe keeps moving in on him to eat it! Once I get to the regular feeding time in the morning I think it'll be fine.

Keeping both doors closed where the litter boxes are concerned. I'll likely hear a kitty scratching at one of the doors to get in and I'll get up and let them in. It's usually first thing in the morning so shouldn't be too bad.

Thanks everybody.
