1. How to train the cat to not antagonize (or harm) the birds? (sub-question-is a kitten best?)
2. What cage is best?
I have been researching Q#2 this evening and think an acrylic cage might be just the thing. Of course, Mary ann, and the offspring (Boo and Magoo) were essentially free, and Sutcliffe cost $20. But pets are the gifts that keep on giving. These cages aren't cheap! (aren't cheep, hahaha).
Here are two options:
http://www.acrylic-bird-cages.com/samples.htm . This isn't a very good website, but it might be a good habitat.
and
http://www.kingsolomoncages.com/specials.asp (scroll down to see the side klean version...simple design...).
The sub-issue/question for the acrylic cage is: now that the birds are so happy climbing around on the side of the cage, will they be bummed out by an acrylic sided cage? this could be dealt with by a ladder/climbing system along the sides (have C and B and their kitty Lily inspired this ladder thinking?...gee the puns are bad tonight!
