Oh! Well that's a great start for your kittens!
One thing you can do to save some money--YOU eat the chicken breasts, and buy chicken thighs, gizzards, hearts, livers, drumsticks instead for the kitty! The reason is that you want the cats to get lots of taurine in their diet. Taurine is an essential amino acid that is absolutely required in cat food, and is loaded in raw meats--especially dark meats. Cooking destroys them as well as digestive enzymes and proteins naturally found in raw meats, so never serve it cooked. Taurine is also most abundant in working muscle meats, so that's why you want thighs, drumsticks, and heart rather than breast. Hearts are considered muscle meats rather than organ, and it's the hardest working muscle, so it will have the most taurine content. Gizzards also work hard in grinding seeds, so that's also considered muscle meat, and the chewy texture is excellent on kitty's dental and psychological health. Don't be surprised if you hear your tiny kittens start growling while they eat, it often happens in the beginning, and quite normal...it's their little carnivore coming out!
Ok...I'm done with my raw speech for now.
For Abby, let's see...how long has she been eating kibbles? The longer the cat has been eating it, the more difficult it is for them to transition. Has Abby ever eaten canned before, do you know? Sometimes it is a matter of finding out what types of canned food she likes...
