Can umbilical hernias affect an old cat? My cat is 13, and her whole litter has umbilical hernias as kittens. They all had surgery. I adopted her from a breeder, who told me about the surgery, but said I didn’t need to worry about it. I soon forgot. 13 years later, my cat has been a regular vomiter for probably 12 years. But recently it has increased to multiple times per day. She has other health issues, and this piece went untreated until she began losing weight and not eating. I got her an ultrasound, and ultrasound vet’s results were pancreatitis and “moderate diffuse infiltrative small intestinal disease DDx Lymphoma vs IBD, less likely eosinophilia enteritis.” I have not yet gone in for a second opinion from another vet. She has been getting steroid injections every 3-4 weeks, and had all but stopped puking. The last 4 days she has vomited 7 times. Is it possible she’s had a looped hernia this whole time, and only now experiencing symptoms worse than regular vomiting? Would that have been apparent from the ultrasound if the vet was unaware of her history? I am afraid to ask my regular vet because I don’t trust her.
