Sage is acting really strange all of a sudden. I just woke up to her making a strange sound. She is in her litter box, and she is opening her mouth and moving her tongue around really fast. It is like she has something stuck in her mouth. When i try to pick her up she closes her mouth and wont look at me so when i put her back down she tried to bury her face into the bottom or side of the cage. She is also making a chirping noise. When she digs her face into the cage it looks like she is falling almost. It is just so strange. Does anyone know what this is? Its 3 in the morning and i cant take her to a vet this second!
