Oh good lord, how cute! They are going to have such a blast growing up together! I made it a year, almost, before I couldn't stand it anymore and got Keegan his little sister. It's so much fun to watch your furbabies enjoy each other. (At our house, the zoomies include our three-year-old male cat--he thinks the pups belong to him so he leads the races!)
Congrats on your precious pair.
