Talisker never seems to bring half eaten rodents and birds back for me.
The one time he did do it, it had just started raining heavily and there was a "kerthud" from the cat flap, indicating his arrival, but no "Meow" announcement from him. Looking in the direction of the cat flap, he appeared with a mouth full of rodent, saw us, and promptly legged it back out the cat flap.
I felt slighted, but also somewhat relieved!
The only thing I've had to worry about recently, has been the odd bit of cat vomit, and apparently occasional vomiting can be a symptom of hyperthyroidism, so maybe this will stop with the pills/surgery/whatever to cure it.
