Hey all i am new to this forum so ill say hi my name is Dave nice to meet you all now for my problem. Me and my partner went to buy a kitten the lady had 4 kittens and 2 had been sold the other 2 were left we only wanted 1 but the other only had 3 legs and probably wouldn't have been adopted so we took them both as they were brother and sister and better to keep them together. When we got them Blackjack (Female) kitten used the litter tray straight away but Socks (Male) kitten has never used it we have had them 4 weeks now and tryed everything we have 2 litter trays one in the kitchen and one where socks had been weeing and pooing but still does not use it. I have and still try putting him in the litter tray 10 mins after feeding and 2 - 3 times per day so he knows where they both are i have changed the litter many times using 4 different types then used soil then i used just paper but still will not use the tray. It was all fine as we expected to have a few issues as you do with pets but Blackjack (Female) has started to copy Socks (Male) kitten weeing on the carpet but not only this Socks (Male) has started to wee and poo on the sofa and he only does it when we are out of sight and i cannot put a litter tray on the sofa really lol nothing is working at all i have read every topic on the net about litter training tips and nothing works at all so please help me if he keeps weeing on the sofa he will have to be put in an old rabbit run in the garage while we are not in and at night and i do not like this idea as cats should not be cooped up so i don't agree with it please help.
