Tried raw... the results are in for Otis
Last night I noticed Otis was acting hungry, yet her dish was full. She had access to Whiskas canned food and Purina kitten chow. Well, she is a smart cat and she turned her nose up to it. I offered her a bite of my mom's chicken marsala and she gulped it down.
I plan to try her on frozen/thawed mice as soon as I get to the bank and go grocery shopping (busy with work and holiday). But on a whim I thawed out a rabbit heart and liver I had in the freezer. I sliced it and offered it to her on a plate. She sniffed it and walked away, only to turn on her heel and go back to it. She seemed to be confused. She wanted to eat it but couldn't. So I did what someone on here said and added a little bit of kitten crack aka tuna juice. Just enough to sweeten the deal.
Instant success. She ate it all, then went back looking for seconds. I feel good about trying whole prey out. Yay!
