My tiny tiny little cat brought in a live pigeon, through the cat flap, and deposited it (still flapping) at the bottom of the stairs. I heard this almighty racket and looked down to see this thing flapping around with the two cats just watching it. I rescued it, but unfortunately it had a broken wing and had to be put down. But at the relative size of cat and pigeon.
The other wonderful incident, was an unpleasant smell in the kitchen and the same cat sniffing around the fridge. We checked everything, finally moved the fridge and out popped a putrifying mouse. Lurvely.
Actually, I hate this side of having cats. Thank god only one of the them is a killer. We don't have a cat flap any more so she stays outside until she's finished with them. I still manage to rescue a fair few live creatures though.
