I'm showered with gifts from my cat Bob, this month so far, 6 mice 4 alive 2 dead, one taken apart on my kitchen floor through the night and and left on display for me to discover in the morning. I woke up with a half chewed slug stuck to my leg a fortnight ago, thanks to bob. Oh and lets not forget the frog, with only 2 legs working, cheers Bob.
All cat owners should have it installed. My cat is loving it ...
We've has one of these for a couple of years. It works great. Unlocks as soon as our cat sticks her head in it, and the batteries last a long time. The draft sealing isn't very good though, but it does at least hold shut when it's windy.
I still get unwanted visitors, LIVE MICE, my cat gently carries them in through the flap in his mouth, then releases them in the house - for sport. I'm still waiting for them to invent that facial recognition flap, that doesn't open when the cat has a mouse in his mouth.
Wrong colour, but good shout ;) Genuinely though - he smacks his head on the flap before he gets close enough for the chip to register (lol)
