Yes i'm thinking it over more now. The visiting kitty is so frightened of everything and everyone. Lived only in my granddtr's room due to her Mother and now goes with her to College as her support animal. So it hates other people. my kitty is about 3 yrs old and very scared of the other kitty who is very large. They can be in the same room but not close to each other. These visits are trying on me too.But the plug in Feliway had warnings of fires happening and the spray bottles sometimes only last a short time. too expensive for all that. So i decided not to get any. I put my kitty in my bedroom last night. i can't rely on her cat to stay in her room and do not want a cat fight! (())
