3 categories in different template styles, how to?

Good morning,

I am sorry to bug you with another question.

Formidog.nl is a webshop for animal food and toys, etc.

there are 3 templates:
brown/orange: dogs (formidog) http://www.formidog.nl
pink: cats (formicat) http://www.formidog.nl/formicat
green: rabbits, guinea pigs (formipet) http://www.formidog.nl/formipet

The template are active on various menu items

There is a news section which is set up in EasyBlog
Main menu > Nieuws > Dieren in het nieuws (animals in the news)
http://www.formidog.nl/nieuws-nieuwsbrieven-acties-faq/dieren-in-het-nieuws

This loads in the brown/orange template (which is ok)

The other categories need to load in another template color:
Katten in het nieuws (cats in the news) needs to load in the pink template
Vogels in het nieuws (birds in the news) needs to load in the green template

How to do this?

I have made a hidden menu with url menu items to the categories.
This does not work

I can’t think of another way to go so I need a fresh and intelligent appraoch to this.
I.o.w.: I need your help.

Thanks,


Dick
