So I used the invite to increase the den inhabitantance for a gryphon.... and nothing happened. I haven't seen a gryphon in AGES. It's been these same pets for a very long time. So I finally used my invite and nothing happened at all...

What is the percentage of the invite actually working? Because it seems like mine flopped...

I tried several times while he stayed

If anyone has any good ideas at how to clear my board and get new pets on there I'd be happy to know... I'm a terrible capture.

Thanks

I haven't tried any of the species invites, so I can't say for sure, but I seem to remember that I read that you have to catch all the current pets before any new ones spawn and that includes magician invites.  

You say you're a terrible capture, if you would like some help catching the ones you have currently, feel free to drop me a message.
