@Janneke:
I really like Malaika and Freya. You can always shorten Malaika to Laika ;)
I like Malaika too (I just love african names :D ), Mali for short :)
Thanks for your replies. I've started giving Sonia Glucosamine w/ MSM every day and we'll see how she does. I'll give you an update in about a month and let you know if it's helped or not.
