Hi, its awful isn't it when they bring you presents home First one we had in the house was a mouse, cat just brought it in and dropped it in the middle of the kitchen floor, dead. Few weeks later our other day brought a bird in, I just saw her and ran OH had to come home from work cause I was in shock (yes I know, it was pathetic of me ) by that time we had feathers all over the place. Thats when I realised our days of leaving the doors and big windows open were over.

Think I'd try locking the cat flap for a while if things are getting too bad, as least if you let them in and out you can do a mouth check first
