I am brand new to this site but find it so informative. I have two indoor cats and a little old yorkie. The youngest of the cats (Spookie) has been spraying in various places in my house for almost a year. I am certain it is due to outside cats. I have a neighbor with three cats that are running around and recently noticed a litter of five young adults running together. I was able to trap two of the five and took them to the shelter where I am a volunteer. Since I cought those two I have not seen any of the others. Now to my problem, how can I get Spookie to stop spraying? I have used Feliway, but not everywhere everyday. He is on a homeopathic anti-anxiety drug three times a week. He's been seen by two different vets, one is a behavior expert who put him on this drug. He is also confined in the laundry area when he can't be watched every minute. The stress level (for us) is terrific. I have read all the postings about this but still am looking for help. My Mother-in-law has offered to take him but I can't be sure that a change of atmosphere will make a difference.
