The little cat I have three cats. The mother and two daughters. But the daughters’ birthday are not the same date. One is 13 months, and the other is only 1 month. Recently I teach the little cat how to use cat litter, but it doesn’t know how to use it. It still pee anywhere, it’s mother also doesn’t teach it. So I made a rail to put the little cat in it, but it wants to come out. It try its best to broken the rail, and it’s mother helps it. I am crazy, the rail is not fastness. Maybe I need a cage, until it learned how to use cat litter.
