Rescue Cats and Litter Boxes
If you've recently adopted a kitten or cat who has been rescued from the streets or out in the wild, there's a good chance they may never have learned to use a litter box.
You can change their habit by filling a litterbox with a mixture of soil from an outdoor flowerbed and cat litter. Allow the cat to sniff the litterbox so they'll recognize the familiar outdoor odors. Before long, the cat will use his or her new receptacle instead of hidden corners of indoor rooms.
