Did you see Joe Inglis on The One Show last night ("One, O-nne, Onnne")? You see, it's true about male cats holding in their wee in cold weather and getting urinary tract infections (if they are outdoor pee'ers that is). Despite my putting two litter trays out for Fred during the heavy snow, he always chose to tiptoe his way through the snow rather than use his tray. I guess he had found a reasonable spot to pee that wasn't too frozen. Funny isn't it, you just can't make cats do what they don't want to, even when it is to help them! Stubborn little individuals - that's why I love 'em!
