Ah, you are feeling guilty already!! Just where Mystic wants you to be!!

You need to be firm and NOT let him out - NO MATTER WHAT - He will try everything under the sun from making you mad, to making you feel guilty (already there ) You need to be stronger and fight those feelings off.

Our Fluffy found us 14 years ago, he was around 2 years old already. We then moved to a bigger house, but with coyotes roaming around. Fluffy was no longer allowed outside - at all. It took several weeks of him crying, beating up Willie our other cat, and even knocking over vases, etc. just to get me mad so I would let him out. Needless to say, after several weeks of wanting to "kill" him (not really, but you know the feeling) he realized that he was fine inside, and now 11 years later he has no interest at all at going out.

So time & patience.........lots of patience!!

Good luck
