Ask the Veterinarian/Cat Spraying


Hello. This is not a cat health question, but I am hoping that you can help me anyway as there was nobody available in the cat behaviour section. My neighbours have a big male cat who is not neutered. I have an indoor cat, also male. Since meeting my cat through the screen one day when the window was open, this cat has taken to spraying all over my house. He sprays on the door, the sides of the house, my outdoor garbage cans, and I live in a basement suite so he has even managed to spray on my windows. What can I use to repel him? Most advice I've seen so far suggests spraying lemon juice or vinegar, but these would be washed away pretty quickly as it rains a lot where I live. I don't mind re-applying a spray, but I want to be sure that I also avoid using something that would harm the cat. What would you suggest to deter him?

this is certainly a very big problem, and I may not have all the answers for you. I would also look for some cat behavior experts (jackson galaxy-, dr. jean hofve -  I feel comfortable with the many recommendations at, though not sure how effective it will be. While addressing people who are feeding feral cats, the wonderful alley cat organization has some good ideas - scroll down their page -, and again I see no problems with any of their suggestions, and some will not wash off in rain (prickly wire, etc).  Motion activated water sprinklers that you move around every few days so they do not learn to avoid them. Ultrasonic cat repeller - just be sure to watch your cat carefully to be sure he is not affected by it (read the Early Warning Signs of Internal Imbalance at my website, which also has ways to help your cat stay healthy for much longer than you would believe -  commercial cat spray repellents have predator scents. Speak with your neighbor, who should foot the bill for all that you try.

The only suggestion I have heard in the past that I would not suggest is mothballs.

Good luck.

I can give you the holistic approach to any problem, mostly for dogs and cats and some farm animals and horses. Depending on the condition and the type of animal, I will be able to give very specific treatment suggestions such as what flower essences, homeopathic remedies, nutritional supplements, diet changes, lifestyle changes or herbs that may be helpful - not drugs. I can also suggest where you can go for further education or to find a specialist in a specific holistic field. I can help you understand why your animal is ill and what improvements can be expected. I do not check messages more than every one to two days, so PLEASE DO NOT ask about EMERGENCIES - call your local veterinarian. I cannot diagnose your animal. I cannot prescribe specific treatments. I am no longer very current with conventional treatments, so cannot answer questions on those. I am not an expert on birds or small critters. I am not an expert in breeding, birthing or babies.


I graduated from the University of Georgia College of Veterinary Medicine in 1980 and began using homeopathy in my practice after a client introduced me to it. By 1988 I was using exclusively holistic treatments. I began lecturing in 1987 and have spoken at veterinary conferences, health food stores, people's homes, churches, veterinary college conferences - anywhere people want to learn more about keeping their animals healthy.
