Thanks everyone, I'll follow up on that. I happened to run into a type of animal society today, by pure chance, and they gave me a whole list for the different kantons:

Aargau: www.tierschutz-aargau.ch
Appenzell Ausserrhoden: www.appenzeller-tierschutz.ch
Baselstadt/Baselland: www.tbb.ch and www.tierschutzbund.ch

Bern: www.bernertierschutz.ch, www.tierschutzkantonbern.ch, www.tierschutz-biel-seeland.ch; and www.tierschutz-emmental.ch

I haven't checked any of the links out, but will let you know about the progress!
