Nervous about cat food

[List]

Hi

I'm new to the site, but I need some advice. I have two cats, a 1 1/2 DSH and a 7mos old DSH. I have been feeding them Hill prescription T/D for a while. They have both been doing very well on it, but the Hills brand contains BHA and BTH, a known carcenogin.

I have since decided to look into the more holistic brands, but its hard to get straight answers from sales people.

Has anyboy ever tried Innova Evo cat food? And should I use it even though its very high in protein. And how does it compare to others?

Any advice and opinions would be greatly appreciated. Thanks
