Hi all, I'm new to this group.

We just brought an orange and white tabby kitten home, Charlie. He's 10
weeks old, extremely playful and affectionate--he's the perfect
temperament. We also have a 10 week old Chihuahua--Spike--who gets
along wonderfully with Charlie. They play, they sleep together and
they've only known each other for two weeks.  Spike was first then two
weeks later, Charlie arrived. So far, so good.

When I first brought Charlie (cat) home, he used the litter box when he
was supposed to.  I used PET GOLD clay litter as was recommended by the
person that I adopted Chalie from. He used the litter box for about
four days and then suddenly stopped using it. We'd find kitty excrement
and urine all over the house. The bed, the couch--everywhere. My wife
and I very patiently cleaned it all up but wondered why Charlie stopped
using using the litter box. It's clean, we change the litter every
other day--he was using it--then just stopped.

Does anyone have any idea why cats stop using their litter boxes?  The
only thing I can think of is to leave Charlie in the bathroom for a
while until he uses his litter box again. I took his toys, food, water
and his blanket in there with him. I don't know what else to do.

Thanks,

- Alex
