Poo in, pee out.... Helppp!!!!

[Vovan]

Hi everybody,
that's my first post here and I'm not sure the same thread wasn't created previously - I just couldn't find one... Well, I was purchased the LK 2 weeks ago for my Josef and the problem I have is that every time (mostly in the morning) he makes pee out - he just stand up into the Red (which is on the floor) and miss it... the poo is ok, all in... Every day the same picture - spot is nearby the LK. I tried to attach it on the toilet - no difference, he jumps up, but all the pee goes out. Therefore after two weeks I've decided to put it back on the floor, but it doesn't help. I'm doing everything "by the book", it his own toilet room (we have total of three in the house) and keep it VERY clean, like in surgery... Any suggestion, guys???
