I posted before about my cat getting a tooth removed and her fentanyl patch. She got the patch off last night and seemed fine. Today i got home from work and she was bloated to 3 times her size and crying. I've taken her to the vet and was told they may have damaged her trachea during the tooth removal. X-rays showed air everywhere. They have a needle in her and are trying to massage out the air. I haven't been told anything more except they will call me tomorrow. Anybody had this happen with a cat before? Turns out her excessive purring was not from the fentanyl but because of her breathing.
