hi, I have three female cats. Sarah is the mother and Tibet and Sake are the daughters. Everything was fine for years but that suddenly changed a few weeks ago. all three cats don´t go outside because they are not sterilised.They stay in the house. Sake behavoir has always been a bit ´fearful´ but she just loves Sarah the mother. A few weeks ago she also became very affectionate towards me and sat next to me all the time, which she did not do before. But she also began to attack Sarah and Tibet. She fortunately stopped attacking the mother but still attacks Tibet vigorously. Sarah also began to attack Tibet. Tibet has always been our sweetheart. Sarah has stopped attacking her after I became very angry at her. But Sake doesn´t listen. The only thing we can do is to seperate Sake from Tibet. Maybe we have to search for a new house for Sake but we would like to solve the problem. Any cat psychologists out there who know how to solve it thanks in advance.
