You'll see many claims for the effectiveness of Margosa oil (neem). However, there is also literature to suggest that it is toxic to cats, including a report from Britain that reported 10 or so deaths.
It does not seem to be on the FDA's list of approved drug products for animals.
Does it work? Maybe. Can it be safely applied? Maybe.
However, just because a product is "organic" or "natural" doesn't mean it is safe and non-toxic.
Maybe you could ask the question of a Medhelp vet.
I will have problems in getting those damm leaves, however ...
Could not find them at the natural products shop,someone suggested ask at a veggie restaurant...
Just asked an Indian woman that I know ( tree is quite popular in India, as you could see later on) but she also had no idea about what NEEN was :-)
Dont worry dear,Im not thinking in use gardening products in animals.There are many diferent products made with neen,including especific ones for dogs and cats, as shampoos,sprays or even the use of leaves tea, as you can find on a fast google search - I'm still in the process
NEEN'S leaves are not toxical,they are used for humane culinary as well- this I already knew.There are medicines,also
From what I get til know oil can be not so good for cats as it is for dogs cos it sometimes came added to other products with some toxity
I will put links here when possible
Here goes the first,take a look
