It's been interesting to watch Wylla's relationship with the kittens develop over these past few weeks. It really has blossomed, and now they spend nearly all of their waking, and many of their napping moments together. If they're tucked away in the guest room, she'll cry to be let in.
If she's not feeling well enough to be right in the middle of a romp or a wrestling match with them, she'll watch the antics from a perch.
I think they've been a great distraction for her on those days she's not feeling her best. Also, I think the extra exercise she gets while playing with them is helping too. Since their arrival, the number of "bad days" for Wylla has decreased.
Kittens are good medicine!
