Adore...Thank you so much for all of the information. I am still marveling over the flight feathers thing! Wow! My setback thermostat goes automatically to 65 degrees at midnight and then back up to 71 around 6:00 a.m. so might just "squeek by" temperature-wise. When I had my parakeet I would let him out each day to fly around and he would come back to my finger and allow himself to be placed back in his cage. At the time that I had him, I didn't have cats like I do now. If I did that today I would have to have him in an isolated room with the door closed for his "flying time," judging by how interested they are at the birdies outside at the feeder. It is definitely something to think about. Regarding fish.....now there is a topic that is big in this house! My husband has had fish for 20 years! Right now we have only two tanks set up, a 75 gallon and a 60 gallon. At one time there were four tanks in this house (my son also adopted the hobby and also worked at tropical fish store like you did). We have had ALL kinds of fish (salt water and fresh water). Right now he has mainly African Cichlids in both tanks. The fish live happily with the cats (at least I hope the fish are happy). The cats sit in front of the tanks and their heads go back and forth by the hour watching them swim. The fish don't seem to mind. (Guess they don't realize what would happen if the cats were able to get to them. ) Well, I am babbling, but just wanted to let you know I enjoyed your informative note. There are so many helpful knowledgeable people at Pet Talk!!!
