They didn't need any adjustment period AT ALL. I got rid of their old litter box as soon as I set up the LR, and they've been using it for the past 2 days without any hesitation.
The only problem I have so far, is they both like to watch it spin, and they keep climbing inside of it while its running its cycle. It's supposed to shut off if they step inside during the cycle, but my one kitten weighs about 5.2lbs, and it doesn't always trip the sensor when she gets back in, so she spins around inside while it's turning, which could get kinda messy I would imagine... LOL I've adjusted the sensitivty of the sensor, but it still doesn't always stop when she steps back in, or sometimes it stops, but then starts up again while she's still inside. It turns slow, so hopefully she can't get hurt in there???? Also she tries to climb through the waste portal holes while its spinning... gotta love kittens!
