> I think he was more stressed not being around people. He was purring all the time.
That’s just nuts.
Purring is what cats do because they’re happy; but, it’s also what they do when severely stressed or badly injured. It helps them cope.
That reminds me of The Abandoned by Paul Gallico, a great read for anyone interested in cats. "When in Doubt Wash" is an oft-quoted line from that book, a work of fiction to be sure but an interesting perspective from a cat's view of the world.
If you're on the Kitty Ping List and you haven't yet read this, set aside a few hours. It's time well spent, IMHO.
