Pets and cancer

Some observations about our cats since Betty has been diagnosed with cancer:

1) On the naughty side of the ledger, they see that she is walking with a cane and feel free to cuff each other and to venture into forbidden territory, knowing full well that she can't chase them.
2) Since she's on estrogen therapy and gets really hot on some cold nights, the two Siamese have developed an affinity for sleeping in her very warm shadows.
3) One of the Siamese seems to have become the "nurse." She now sleeps with her head on Betty's shoulder. Betty is going through physical therapy exercises and the cat is joining in. She has lain on the floor next to her "stretching" and showing her belly when Betty does the belly-in-the-air exercises.

Does anybody else have any stories?
