2. Vomiting: Vomiting can be a sign of many different health issues, such as digestive problems, liver or kidney disease, or even hairballs. If your Bengal cat is vomiting regularly, it’s important to have them checked by a vet.
3. Diarrhea: Diarrhea can be caused by many things, including digestive issues, changes in diet, and parasites. If your Bengal cat is having frequent diarrhea, it’s important to have them checked by a vet to determine the cause and get appropriate treatment.
4. Sneezing: Sneezing can be a sign of a respiratory infection, such as a cold, or an allergy. If your Bengal cat is sneezing frequently, it’s important to have them checked by a vet to determine the cause and get appropriate treatment.
5. Coughing: Coughing can be a sign of a respiratory infection, such as bronchitis, or a heart problem. If your Bengal cat is coughing frequently, it’s important to have them checked by a vet to determine the cause and get appropriate treatment.
