Looking for dry - rabbit formula

My cats have been doing really well on Nature's Logic rabbit formula. But my pet stores are no longer carrying it. I'd like to keep them on something with rabbit. I have tried them on grain frees (high protein), but they were too rich (diarrhea). And they've been on Wellness chicken (not grain free) and they had soft/runny stools.

Does anyone know of any other rabbit formulas? Or perhaps something that is a little richer than chicken or turkey, but not as rich as a grain free like EVO or Core?

Thanks.

natures variety Instict has a rabbit

I used Nature's Variety Instinct Rabbit when I was still feeding dry food. Mine loved it but I guess most cats don't?

I feed rabbit wet food occasionally to mine that still eat commercial. They also love duck and venison!

Thanks for the tip.

I checked their website and the ingredients in the NV Instict look pretty good. Although, it's a grain-free, so I'm a little leery. They have never really done well on grain-frees, and I'm concerned that down the road it might not be UTI friendly. Neither of my cats have had UTI issues, but magnesium levels concern me.

I just hate it when pet stores just up and stop carrying a particular food. Although, I understand why they do it. I can get Nature's Logic online, but the shipping is ridiculous. The food is around $14 for a 3.3 lb bag.

Do either of you have advice on switching from rabbit as the main source of protein to another protein? (ie., duck, lamb or venison?)

For example, NV makes a lamb/oatmeal:

Any thoughts?

fish would be my next one... duck is OFTEN to rich for sensitive tummys.... lamb is a HOT meat and can cause more issues ... venison is close to lamb

Instinct Rabbit has a lower protein than some of the other grain free diets so it may be less rich.
