My cat looks perfectly healthy. But the last time that I visited the vet I received a dewormer to apply to his back of neck. I'm wondering if this is absolutely necessary?
I suspect that this is yet another marketing ploy to sell a product whose benefits (if any) does not outweigh harms due to chemical compounds. After all for 50 million years felines did not use deworm products and that does not seem to not bother them much.
