Tonight we're going to spend some time posting Ripley through the cat flap so she gets the idea and then leave her to her own devices. Newt will probably require some more supervision as we've realised it would be easy for her to get into a place she can't get back from.
Be careful posting them thought the flap. I know some folks here suggested this but it resulted in negative reaction with mine. She ended up being scared of the flap for a while. I tried using treats on the other end to tempt her to go through. I also had to tape the actual flap up so she could get used to going through a tiny hole. Then once she got used to the hole, I shut the flap down without the microchip option, then a few weeks later, I turned the microchip option back on and now she loves shooting though the flap for no reason sometimes...
