When I opened the front door this morning my cat was just lying there. She has been lethargic all day. She's usually very playful but today she has been lying around and sleeping. She ate with the other cats but I haven't seen her drink any water. Her eyes are very glossy and she looks so spaced out.
The weirdest thing just happened: When I petted her, her skin popped as though there were air bubbles under the skin. You could feel and hear it popping.
What is wrong with my cat?
