I have two adult cats girls: the first Siamese breed (7 years), and the second Russian blue (1.5 years). They were friends and were inseparable. I was happy: they understood and obeyed me, and I understood them. We had new neighbors on the street and they blew up firecrackers for the Spring Festival. Of course, the cats hid in the basement. A Siamese cat a day later became the same again, but the Russian blue cat became all different. It has ceased to be friends with its Siamese friend and play in general, it is afraid of everything new and especially strangers. It can quickly get upset and instantly get angry (cut my claws when I handed it a treat). One room where I sleep, it has appointed itself a home. And it began to live under my bed, after dragging my rug, although it often hides in the basement. It does not communicate with it friend and does not go out at all. It has become capricious and constantly requires delicacy. And most importantly - the Russian blue does not go to the cat's toilet. That's how it behaves for more than six months. My friend is a veterinarian and advised papers toilet bowl to solve the latter problem. This helped and hygiene became acceptable. But what to do with the rest of the behavior, because I understand that my cat feels bad and her life has become a nightmare. Can anyone give advice?
