There is another kitten younger than them, Sqeaky because of her sqeaky li'l mew. She's from a different mother who is friendlier but has also resisted trapping/handling.
We've taken that kitten to the vet once when it was very sick, but it wasn't old enough to get fixed yet at that time, but it is now so hopefully we can get her in soon.
She's only a couple weeks younger than the siblings, but she's much smaller.
