? Auto feeders

I was reading about these on another thread, but didn`t want to hijack that thread. I just bought one of these for Lulu for night feeding, but I also have two civies who would no doubt help themselves to the food in Lulu's otto. Should I invest in two more feeders? I don't want to isolate Lulu, because all three like to sleep on the bed with me. I fear Lulu would feel left out if I locked her up in my spare room.

 

If you can swing 3 feeders, I think that's the perfect solution!!

At least everyone would have a fair chance at the food!

 

And spread them far enough apart that one can't easily raid the others!
