My new kitty barely eats?

GO TO PET SMART AND GET SOME KITTEN FORMULA. ITS LIKE ENFAMIL 4 CATS. TAKE THAT ONCE ITS MADE AND WARM AND MIX THAT WITH CRUNCHED DRY FOOD. I ACTUALLY WAS USING AN EYE DROPPER ON MY BABY KITTEN WITH CAT FORMULA FOR A WHILE TIL I GOT TIERD OF WAKING UP IN THE MIDDLE OF THE NIGHT TO MAKE A BOTTLE. I MOVED IT UP TO THE MIXTURE AFTER ABOUT A MONTH ON THE BOTTLE SO ID SAY HE WAS MAYBE 2-3 MONTHS OLD BY THEN. MINE HAD THE WATERY POO AS WELL UNTIL I MOVED IT 2 THE MIXTURE OF FORMULA AND FOOD. THEY ALSO NEED WATER, PLAIN WATER. I HOPE THAT HELPS.
