I left our two kittens out for the first time on Saturday after escape proofing the garden. They will eventually be able to climb the fences but are a bit small for now. This morning I showed one that the cat flap door could be moved and approximately 3.5 seconds later they had both nailed it and have been in and out since then.
Should I be making sure they are in and locking the flap when I go out for the time being?
Is it ok for them to be out as much as they want when I'm around excluding the night time? They are vaccinated and neutered.
