The three (of which Snuggles was the last) would readily and loudly purr -- a lot. The other four we have left now will lick us, one will cuddle into my neck like Snuggles did, but none of them purr. Maybe every once in a while we'll get a really short burst of a purr when we are petting them, but it's over before you can enjoy it and it doesn't recur.
I guess I'm just going to have get used to not hearing any purrs anymore, but as I pet my remaining pigs, I can't help but really miss the purring of the others.
I don't suppose there is any way to encourage purring? (Talking out of my grief here, so this is probably not an intelligent question.)
So half of the guinea pigs I've had purred a lot. I didn't realize it was rare. Instead I thought the non-purrers were the abnormal ones.
Sigh. I miss the purrs. They are so joy-giving to me.
My youngest guinea pig purrs sometimes, but I think she mostly purrs our of confusion (so I guess "burring" like Lynx said). I always took my piggies turning into pancakes (like flattening out and relaxing) as happy signs when I hold them :)
Several of my pigs do the flattening out thing on my lap, so I know what you mean! That's how I know Mouse is happy. She doesn't purr. At all. Like ever. But she will make noises and will flatten out on my lap or chest when I watch TV. She doesn't like to be held for an hour like Snuggles did, but very few piggies would like that.
Mouse is very quiet, but that's not why we named her Mouse. When she was born she looked exactly like a little mouse, which is why we named her that (she is dark brown all over, smooth hair).
