Yes. I carry both my girls in one carrier I bought at Trixie and Peanut. They are 2.6 and 3 lbs so i think it should fit your 2. I love it! It's the size large, the small won't fit 2 pets and it has 2 security buckles and plenty of storage space and just looks like a real purse. Here's the link and pics of my girls in it.
