Millie is a sweet 3 year old girl. We adopted her almost a year ago,but it seems our other cat gets her very upset. Based on our observations, she needs to be the only pet in the house. When she is stressed she tends to urinate outside the litter box, but it is not related to any medical issues. Millie is full of love and enjoys playing and purrrrring. We are absolutely heartbroken to give her up, but feel she would be happier as the only pet in the house. She is good with kids and adults, it is other cats and dogs that stress her out.
