Missy is the only one that spends much time indoors. Mama will do a walk thru to see what is going on, but will return outdoors. Being male, Iggy is still very attached to his mother. Missy was literally with her mother when Iggy was born so she is a combination sister/aunt. When Mama was under the bushes nursing Iggy, Missy was the lookout. Iggy will remain primary outdoors as long as he stays around here. I can not handle three cats inside. While, Iggy can be handled, he still prefers cat companionship to human. You have to catch him so you can pet him, but he is docile while being held. Mama does not like to be held, so I think Iggy has a lot of her personality. He is definitely built like her. As you can tell, I love to watch their personalities.
