Your cats have learned to accept you and all of your quirky habits right?  Did you get used to all of their coughing up of hairballs? Cats swallow a lot of fur when they groom themselves.  Sometimes the hairballs take care of themselves and sometimes your cat has to cough them up.  Some short haired cats have problems vomiting hairballs but there is a way to manage it by modifying the fiber content in their diet. Your veterinarian will check your cat for any possible problems then help you find ways to help cut down on hair balls. There are many hairball elimination products on the market which can really help. Always consult with your vet first and don’t get too concerned when your cat coughs up a hairball. It is perfectly normal for them to do this one to two times a month. Any more could signal another problem which your vet will identify.
