Last Thursday while sitting in the sun on the screen-in porch, Nibble started screaming. She has been napping before she started screaming. Afterward she calmed down quickly and ate, drank, and pooped as usual. Two days later she was relaxing in her cage and the same thing – screams, then goes about her normal activities. Sunday night she screamed again, quiet Monday, then today she screamed twice. She is acting normally otherwise, she eats her greens, pellets and hay as usual, is drinking the same amount and there is no change in poop amounts or her interacting with her people or cats. Nibbles and the cats are not left unsupervised together and she and the cats either ignore each other or sit near one another. We have had no changes to our household routines. Any ideas? Is she hearing something we can’t? I know we have hawks and owls that live near our house, could she have seen the hawk while on the porch?
