I would start out slow with the Missing Link - I only gave Oscar a tiny bit (maybe a 5th of a tsp) to start out and gradually increased the amount of the course of a week or so. The first time he ate it he was smacking his lips as if it was peanut butter! He ate it right up though - maybe try a smaller amount with Chloe until she gets used to it. I mix Oscar's in with his kibble and a bit of warm water so the ML powder creates like a gravy. If you give her too much too fast she'll probably get diarrhea.
Oscar now gets half to 3/4 of a tsp in his dinner only (not his breakfast). To me, a whole tsp just seems like too much for these little guys.
Hope this helps!
P.S. ML might also help with Chloe's hair breaking and her itchiness - it seems to have helped Oscar a lot!
