Glad i could help. When I was doing my own research on toilet training, a lot of the sites suggested aluminium roasting pans, which are hard to find around here (at least the large ones). Besides, I've been lurking around this forum for a while, so I figured I should contribute back.

@Luigi .. although i could be wrong, i doubt if the toilet training is the cause for the blood in urine. My vet knows that the cats are toilet trained, and he's pretty supportive. If toilet training was bad, i'm sure he would have said something. But then again, I don't really know...

@ zzorro, waiteng74... good luck. Do give updates on your progress if you decide to take do it

Well, probation period for guinness continues. No accidents lately, but I have to get up earlier to make sure i catch him if he started scratching around at the wrong places. In fact, i just finished my get-your-butt-on-that-toilet-seat-young-man routine with guinness just now, so it's not quite over for me.
