So I found this little sombrero -- I have no idea from whence it came. I figured, since cats love to sleep, perhaps the the little hat would further improve the quality of their siestas. Phoebe looked so natural in the hat and I sensed her dropping into a deeper state of snooze as soon as I placed it on her tiny head.
Saffy, on the other hand, decided the sombrero gave her angry siestas. I just think she needs a bigger size.
