Instead, I found a recipe – for a neem leaf tea anti-flea spray – on www.naturalnews.com. The entire article, How to Use Organic Neem Leaf for Flea and Tick Control for Cats by Susan Lavarie, is interesting. I’ll just quote the recipe and instructions here, and I’ll add the caveat that I don’t know anyone who has tried neem leaf tea for flea control. It would be great to hear in the comments from a cat guardian who has. I myself can only conduct the trial on a certain little dog – not the same thing, I know – but I will update this post with the result.

“Recipe for Neem Leaf Tea for Flea Control in Cats

By far the safest method of using neem as a flea treatment for cats is by using the neem LEAF not the oil. Neem leaf is very safe even when ingested in small amounts and shows no adverse side effects.

-Purchase fresh or dried neem leaves. Place in a bowl and cover with water in a ratio of 1 Kg of leaves (about 2 Lbs) to 5 liters (6 quarts) of water and allow them to soak overnight. Keep water at room temperature. The next day grind up the leaves in the water and then filter in two stages. Pour the mixture through cheese cloth and then through a filter paper like a coffee filter. The final result should be a clear liquid tea.

-Spray neem tea on cats if they will allow it or apply liberally to a cloth and then rub the cat down for an excellent flea repellent. Repeat often for pets that spend time outdoors. It may be used bi-weekly in the summer months for flea and tick control.”
