I mean, it's been 2 weeks...and I know the mama has been around... I saw one other with this one in a box the previous weekend to the time I got this one. Saw the mom a couple days prior to that. Some guy said he would take them. I'm figuring he left this one, who wandered away.
If there is more where i suspect, I can't reach them. It's on mama cat. This one was alone and cold, and I do/did worry about others. But yeah, 2 weeks, I'm sure she's taken care of them. If they exist.
