Hints from a Mom to4, We found the first cat thinks she owns you. Has her own litter box, then my GD dropped off a cat so little, First cat tolerated the newcomer as she still ruled. They both grew up and of course we had the operation. They are outside cats unless its bad weather. During the bad snow and so cold someone left a small female cat on our corner. We are the only house close. Being an old softy I took her in made appt for her surgery. Came into season. She had 5 adorable kittens. We got one a good home and kept one very smart and so pretty one. Took the rest to the vet so he gets them homes. The older cats tolerate Baby cat and Muffin. They are outside as they will not share a litter box. When baby comes in she runs to a dark place and does her job. I have tried spraying her with water. It did not work. I noticed like babies they go right after they eat. So be quick if you bring them in. They will decide who the alpha cat is..
