is this good dry food?

nutrience natural ocean fish duck? 

The food source is good in general however there are other issues with this mix but I must ask why not canned or raw.  There are many benefits by going with a raw or canned diet and your cat will appreciate everyone of them.  Kibble in general is not recommended and is usually a last option but I also realize that some owners have an extremely tough time transitioning their feline over from kibble.  Some cats just will not eat anything but kibble.  Now in regards to the Nutrience Natural Fish and Duck.  Is there a reason you selected this food, allergies or IBD could be reasons.  The biggest issue I see is that this kibble is a fish based diet which may not offer the meat based protein source required for felines even with the duck.  You should probably supplement that with another protein source and if your going for a hypoallergenic diet than venison or rabbit are both great choices if not than any white or red meat source will do.  

As far as other kibble goes there are probably some better choices but that is based on a no restriction.

 i got a friend who i been trying to get them to switch to canned, i also tried to tell him kibble is not very healthy for them, they shouldn't have problems transitioning to canned or raw as they used to be my cats and they loved raw, and canned when they was with me, they also hunt, he chose it because it looked good. i was wondering if it did have too much fish
