Remember, Polli has been through a lot lately. Frankly, it is a nasty wet and cold here in NY so maybe it is just the weather. Take a deep breath. Call the vet and see what they say. Sending prayers and hugs.
I'm so sorry for your loss. Only one photo shows on my screen but that one photo is of a creature with kindness and wisdom in her eyes. I'm glad you were able to share that with her.
