Kittens are now 4 and a half months old, and we're just about to start letting them go outside.
This will have to be done in phases - firstly, out into the enclosed back garden, till they get used to that, and then out through the catflap, which goes out into the street.
Until we've done both, so we know that they can get back into the house, obviously we will keep the litter tray going inside.
We've had several cats before, but I just can't remember how we dealt with the removal of the litter tray! (In my defence, the last time would have been about 17 years ago!)
So what tactics should we use to encourage them to go outside, so we can get rid of the tray?
