Thanks everyone for your nice comments. Arlene, they still get along amazingly well. If they do scuffle they usually work it out among themselves, but they are constantly supervised in case of trouble. They have taught each other bite inhibition very nicely. The lion weighs 65 pounds, Cairo a little less, but still relatively equal.
We have started separating them for a few hours a day to wean Koza off her company. He stays at Lion Camp and she goes for a long walk and has some one on one time with us. This has had a nice side benefit - the exhibit animals are becoming accustomed to seeing Cairo around, which helps when we have service dogs in the park. Cairo has also learned not to bark at the elephants. This week we will introduce the cub to Mina, one of our adult female lions. This will be done through an intro screen so they are not in direct contact. It's time for Koza to learn that he's a lion and not a dog, especially as his future will be as a breeder at another facility. His genetic line is very important to the North American lion program - we have to get him ready to form his own pride one day.
Edited to add that Cairo has a forever home waiting for her with one of our animal care managers. She will have a great yard and some dog buddies, and will be very spoiled.
