phew - he's back in now and chowing down on some grub - his sister Jessie had been v opportunistic and eaten both lots of food whilst he was missing

OH said we shouldn't give him any more to teach him a lesson but I didn't think that was fair!
The little toe-rag has discovered the front garden - he gets out by going under next door's buzzer entry side gate (her front door's round the back of the house). Anyhow's, I said I would go and sit outside to see if I could find him when OH had already been out the front and swore blind he wasn't there. However, when I went out, next door's security light was on and Cosmo was just sitting there, squeezed between the hedge and the gate. He didn't look v happy and only came up to me when I called his name v slowly and I then grabbed him when he got close. (Yes, there were a couple of pathetic meows but not too much struggling, which goes to show he was quite subdued - not his usual self at all - and he's now all over me)
So, am wondering whether something spooked him and he got confused/frightened about coming back

? Question is - what do we do tomorrow/next time the weather's nice enough for him to go out...
