I thought he looked about the same size as Paizly. She is 4.3 lbs. And she just got her last round of shots along with rabies this past Tuesday. And she is scheduled for her spay on the 18th.
Just because they are the same size doesn't mean they are the same age, but they're probably close. Paizly is approximately 4 months old. But I think she is small. She only gained .3 lbs in 4 weeks, and she eats a lot!

I hope you can find this lovie kitty a home. He seems like he really wants one.
