Having a mutiple cat  home it's hard to find a food that  is good for  all my cats. Purina Cat Chow Indoor Formula is it. My cats range from 6 yrs to  a few months old and even a female with  new born kittens under 2 weeks and they all love  it.  I was having issues with  my cats  and  other cat foods I had tried  and  nothing  sovled any of those issues  I was having with hairballs and smelly litter boxes. I switched to the indoor formula  to see if  it  would help with the  odor  problems  with my  oldest cat  since  canned food  just seemed to make matters worse ...
