So sorry to hear about Tima. I agree with columbine: try a limited ingredient diet. Royal Canin uses corn and corn is high on the allergen list. One of my cats cannot eat anything with grains.

Currently I use Innova, and Wilderness and Spa Select, both from Blue. Right now both brands are good. Vetrinarian's Formula is also excellent.

Spunky has leaky eyes that are sometime reddish, and the vet gave me a steroid/antibiotic ointment to use. It doesn't cure the virus but does keep it in check. I apply it on a regular basis.

My thoughts are with you.
