Bad Gas on Chicken soup for cat lovers soul

Wow! Crosby and Sammie have been on chicken soup adult for about 2 1/2 months now. The gas is unbelievable!!!! I hate to switch back to proplan cause i know chicken soup is a better food but there is a $$$$ issue. With 3 dogs and 2 cats i do have to limit the price of their food. They were fine on proplan but had some shedding issues. The fur is fabulous on chicken soup but the gas is un-be-liev-able!!! Any suggestions?

It is likely the duck .... if there coats are doing well try solid gold or natural choice

I had that problem on Nutro kitties have to be such a pain, don't they?? maybe you could mix the pro-plan and chicken soup? get the best of both worlds?
