HELP!! We adopted my indoor cat from the animal shelter almost a year ago. He is almost 2 years old. He is litter box trained and has always been fine until recently. All of a sudden he has started peeing all over the house!! He has one certain spot that he just keeps repeatedly going on and then he has gone another place once. MY HOUSE STINKS!! :grump: He still goes in his litter box and he does not poop anywhere else but in the box. WHAT IS HIS PROBLEM!?? Is he marking his territory or something?? (BTW he is a nutered male) Please help me figure out what is going on or I am going to have to make my precious baby and outside kitty. Also.....how do you get cat pee smell out of the carpet??!!
