G'mornin, snails!
Sorry I didn't give an update sooner, but LevLev was back to his old self right quick. The "instructions" said to keep him separated from other cats so he could sleep...yeah, no way that was happening. He and Zuzu missed each other way too much and I could only stand the meowling for so long, LOL.
I spent a lot of quality bonding time with Zuzu while waiting for the appropriate time to pick up LevLev. Finally, after playing with her for a bit, she snuggled up next to my thigh while I was on the floor reading. I took the chance and started petting her...soon after, the purring began. YAY!!! And I got to rub her belly for not a short time!
