I have a pair of 1 year old siblings who are not yet roaming freely between inside and outside.
They have been very nervous if the outdoors and it has taken a lot to get them going out at all. I have been leaving the patio door open over summer so they can come and go as they want, as far as I know they have not yet left the garden, but will spend 30/45 mins exploring out there now.
However they will not use the cat flap. If I don't open the door then they don't go out. Any tips on how best to encourage them?
