When I was little I some how got the idea that cats only pooed and did not do any weeing. When I told my mum that cats could not urinate, she though it was funny and told me that it was totally wrong that cats do not wee and if a cat could not do a wee, they will eventually burst into a big gross explosion of urine, blood and guts.
