Need suggestions for chicken free cat treats.

I'm going to be cat sitting for my daughter and her partner for a few days next month. This will consist of going over to their place each day to refill food and water dishes as needed and scoop out the litter box.

This will be my second time doing this. Banshee and Pooka are very shy little girls, and when I went over to take care of them last year, they spent most of the time I was there hiding. By the last day, they were showing themselves more but would still dart away if I got too close.

I want to make friends with these girls and would like to try offering some yummy treats to help them associate my presence with something positive. The problem is, daughter says Banshee is allergic to chicken, so I need to find something without that (very popular) ingredient.

I have a few weeks to get ready, so I'm starting to research what's available out there. I was wondering if any of the cat lovers in thIs group might have any suggestions.

I'm tired of my grandkitties thinking of me as the strange lady they have to hide from when she comes over and want them to start thinking of me as the lady who comes over every now and then and brings them *DELICIOUS THINGS*!
