Several times a day! I just say "Kiss kiss", and I usually get wet, slobbery kisses (she uses a lot of tongue)! And sometimes I just hold her and kiss her face repeatedly and she'll close her eyes and stay very still ... almost as if she's saying, "Okay ma, get it out of your system!" When I finish, she slobbers all over me to return the favor. lol Life is good.
Technically, no ... but my vet said that some parrot species (such as lovies) can "store" a bit of regurgitated liquid in their throats as a sort of lubricant at times when they eat. So, it isn't saliva but throw up ... which is really disgusting now that I think about it! lol
