If you are going to part raw feed Holly i suggest some research
Mika needs a meal that weighs between 2-3% of her ideal body weight.
You can use perhaps a chicken wing, a sprinkling of pre made mince and maybe some liver, but for a while i would just stick with chicken as introducing too much variety in one go can lead to the poops.
I used to part raw feed Ruby and always found undigested bone in her poo and if she had too much bone in one meal she would sick it back up. Since she is fully raw fed this doesnt happen any more and i believe it is because the PH level in her gut is more stable than when i combined kibble and raw, so you will have to monitor how Mika adapts.
It is a scary thing when they gulp bone so you could always hold one end for Rio or smash it up a bit before feeding.
There is a FB group called The Raw Feeding Community it is mainly American but many are part raw feeders maybe you could get some more advice there too
