Strange Kitten

Hello everyone! My cat had 4 kittens a month ago. Of the 4, 3 of them are super playful and love to run around. The other one curls up in a ball and watches the others play or will sleep. She can walk pretty good (besides the fact she's still trying to get used to it) but hates doing it. I know that sounds weird but it's not like she is sore or anything, it just seems she hates walking. And when she isn't laying with me or her mom, she is shaking. When the other kittens feed from the mom, she just kind of lays over her mom and sleeps. Idk if she's feeding whenever I'm not there or what. The only reason I'm concerned is because the last time we had kittens, one had accidentally gotten under my feet and broke his pelvis and passed away the next day. I was devastated so I have been very protective of these kittens and that's why I'm so worried about the way this one kitten is acting. If anyone knows anything it could be please help me! Thanks!

I would take her to the vet that's probably your best bet with a diagnosis.

Do you see the kitten nurse from mom? How long have you noticed the shaking? Is she smaller than the others? I wonder if she gets enough to eat. Do you know how much the kitten weighs?

I have not seen her eat from mom but I put a small bowl of water out and she drinks that. She only shakes when she's on the ground after walking because she wants to lay back down with mom

And she isn't the smallest. She has a pretty fat belly

It may be so, she dont being so vigorous as the others, is pushed from momma teats by the others, but she apparently eats - she prob does it when the others are sleeping.

Still, watch out if she gets enough.  If she drinks water, you can give her goats milk too.  Its always a good supplement, whatever the need.

Otherwise, I would suspect some problem.  Perhaps heart weakeness?  That is why a vet check up is so good, to get sure knowledge.
