With 4 benglies I have to be careful what food I feed them - 2 of the benglies have never had a problem and neither have my 2 moggies but the other 2 benglies are quite "sensitive"
I used to feed Arden Grange before I got the Benglies and always got on really well with it, the only reason I changed was because I wanted a grain free food and also would have had to feed separate foods for kiiten and adult. They are all on adult now so am hoping the Arden Grange sensitive works out.
The RC sensible was a No no with the Benglies.
