What Consistency Of Poop Should A Kitten Have?

my cat has been pooping once a week since she was 6 weeks old.

She’s almost ten months now and her poop is very loose but clearly defined, not runny at all! I’ve tried mixing in canned food with the kitten milk formula to see if it will help, but I’m afraid that maybe this isn’t normal?

My vet said they are supposed to have little hard stool balls by this age…
