A kitten came into our garage this weekend and grandchildren want us to keep her. She looks to be about 3 months old. I have 2 other cats..one is 7 yrs., the other 11 mo. I have started trying to litter train the new kid..so far she will not stay in the box and has pooped on my floor twice and on top of the counter in the utility room this morning…however she did cover it with business cards, paper clips, leaves off a plant, anything she could find. She had also peed on the counter the nite before. My other 2 cats are stressed and afraid of her but she is definitely not aggressive. I wondered if I put her litter tray on top of the counter might help acclimate her to the litter box. Please help or I will have to get rid of her.
