we lost one of our Siamese, leo to Kidney failure in the autumn. Lexie misses him so much and recently started biting the furniture,ripping at cloth and getting really angry and frustrated. I had a had some Pet remedy and sprayed her bedding…..she is calm and loving again. I cant praise Pet remedy highly enough. My bottle is a couple of years old now – how long is it good for – because we are collecting a siamese kitten in 2 weeks and I need to be sure Lexie will remain calm and not take against her. She really needs the company!
