It's quite hard to spot distress in cats, they can be pretty ill and not show a sign, you can in fact poison them with antifreeze and for them to not show any symptoms until it's almost too... ...wait, why am I telling you this, you already know, silly meYes its absolutely terrible - just look at the cat he looks so distressed....

Anyway, a hunting animal on a lead, 10 minutes outside, that's never going to be healthy is it? Let's not use Americans as a guideline for sane behaviour,
I don't even put a lead on my dog.
