At first my cat, Riley, was sick. She had been stepped on a couple weeks ago by my sister right in her midsection and she started acting weird yesterday. My mom thought it was a spinal injury or there was a hole in her diaphragm and her organs were going up into her chest. But than my other cat, Charlie, started showing symptoms today. Riley can barely walk, when she does, she falls over. Both of them are sleeping a lot, and Riley hasn't been peeing or pooping. Charlie was really hot, according to my mom. They haven't had their vaccines, yet. Does anyone know what might be wrong with them? They have an appointment with the vet tomorrow, but I'm worried.
