If I were you I would look into getting a kitten. I tried to switch my two adult cats over and they were not interested. Tucker was a bit interested, but not totally (he was eaten by a fox last May) and Tilly pretty much starved herself into hepatic lipidosis (essentially liver failure, we had to rehome her because she wasn't doing well with all the dogs when Tucker died).
A girl brought in this tiny 1 pound, emaciated kitten into my work because she was vomiting and very sick. The next day she called in and told us that she didn't want the kitten anymore, and asked if we could find her a new home. So with both of my previous cats gone...I pretty much got suckered into taking this new kitten home :biggrin:
She has been so easy to switch over to a raw diet. She will eat anything. We are constantly having to lock her up when we eat, because she has been known to steal food right off our plates LOL.
As far as the diet goes, she just gets a bit of what the dogs are eating. We also don't really follow the 80/10/10 rule either, even with the dogs. We just use it as a guideline.
We also go to the asian market here and get small, whole, fresh fish for her to eat. Most of the time she eats the entire thing, but leaves the heads sometimes.
Whole, frozen mice is another thing we get for her. She eats them completely in about 30 seconds. We get them from a reptile store. We tried giving her a live mouse once but it kept biting her LOL...so we brought in one of the dogs to kill it for her. I'm pretty sure we are going to try giving her a live one again, now that she is a bit older and bigger.
I have constantly been looking for small birds, quail and such, at the asian markets too, but haven't been lucky yet.
She will eat chicken backs just fine too.
As far as quantity goes, we just eyeball it. I have never weighed anything for her or the dogs. We just estimate what looks like an appropriate meal for her size. If she comes back still hungry we give her a bit more. If she starts cleaning herself after eating we know that she got enough to eat. She generally gets fed only once a day, maybe twice. Again, cats are totally different than dogs. Kittens don't really need to eat quite as constantly as puppies. They are not growing as quickly or as much.
When she came to us, she was in horrible shape. Of course we switched her right away and now she is really healthy. She will most likely always be small for her age, she only weighs 4.5 pounds at around 7 months (kitten generally gain 1 pound for every month of aging until they reach full grown). She is doing fantastic!
