That is too cute with the chicken and two cats!!!!!!
I wouldn't worry too much about your kitty eating like a horse. Different cats have different requirements. She may be going through a growth spurt and need more food than the can or the vet recommends. And those are no rules, they are only guidelines.
My cat Nemo was like a bottomless pit when we got him at 9 weeks old. He would eat and eat and then eat again. I would feed him as much as he wanted at every feeding, I fed 3 to 4 times per day. He still eats more than most other cats I know and he is a tiny little thing (but don't underestimate him, he rules the house and his 5 doggie companions


). He is 5 years old now and still has his moments when he eats like a horse, and then the next day he is Mr. Finicky, just looks at his food, gives me THE look and strolls away, pouting

.
There is no one size fits it all and there is a lot about cat or pet nutrition that doesn't fit the "guidelines" established by us. Just goes back to cats have a mind of their own and rarely give a rats patootie about what we want or what we think
I second Kathryn's request about pictures!!!!! All the best to your new family addition.
