Product category listing

[ Moderator note: moved to Fixing WordPress. ]

Hi!

I have a big problem, what i cant solve yet.
Im using woocommerce and woof products filtering.
I have a category for animal foods. Im searching how to solve my problem.
I have products under my dry foods category, and i have category for taste too, but i cant put it under the dry foods category, becouse i will have dry foods for cats and dogs too, but i cant give a subcategory for taste and etc for every food.
So when i click on the menu for dogs, i cant filter for the fish taste, cos the taste is not under dogs category, but the dog foods are in the taste categories too. How can i put the main categories under every subcategory for filtering?

Anybody have or had the same thing with category?
Please help me how can i do this with my products.

Thanks
Andrew
