You can tell by the spots on their noses. Harriet has a sprinkling of black on her nose, but Ivy has distinct black spots. I am glad to see them together Ivy, the mother, seems to have had enough of parenting and has been growling at Harriet so that she can have that heated rock all to herself. Her other daughter Sherry is or has gone to Canada and her son, Bailey I is his name, is off exhibit. It is still breeding season so you might hear a loud cross between a meow & a roar. They have been making a racket for the last few months, but hopefully that will mean there will be some cubs this summer.
Did you get any of the two baby giraffes? Also the snowy owls have been very cooperative lately.
Glad you had a good day.
