I have a bit of a silly problem. I'm pup sitting, and I'm having trouble with two pups one lap. Missy usually isn't interested, but she is today. Kaji is jealous and refuses to share. I try to make room for both, but they can't get comfortable. Missy is 8 lbs, a little taller and longer than Kaji. Kaji is 7 lbs. How do I get them to comfortably share a lap?
