Quasar stopped trying to bolt over the winter but, more recently has started trying again.
He got outside a few nights ago when my hubby went out in the backyard and was not watching for Q. When I couldn't find Q in the house later that evening, hubby swore up and down that there was NO WAY he could have gone outside.
When I reminded hubby of his brief trip out the back door he was still doubtful but, after a long search through our house he finally went to look outside. In the dark, it is almost impossible to find Q if he escapes. Hubby said he heard Q talking to him from the bushes but could not see him. He came in and grabbed DaBird. I watched hubby lure Q from the bushes to play with the feathers. Every time he lunged for Q, Q ran off. It was a really funny thing to watch! (and a great game for Quasar)
Finally, I went outside, took DaBird from hubby and lured Q right to me. I scruffed him and brought him inside. I laughed at hubby. He did not find this amusing.
Ultimately, what we have had to do to prevent Quasar from going out unattended, is make eye contact and speak to him before we open the door. When he knows we are watching, he doesn't try to run. If he should try to bolt, we will be ready for him.
I think that as far as your kitty escaping out the door is concerned, it will be easier for you to train your family members to watch for his attempts than it will be for you to stop his exeunt.
