Hello all!
One of my cats has always been prone to vomiting. Multiple trips to the vets over the years has always resulted in a clean bill of health and diagnosis of hairballs. He is twelve years old and very active and happy/healthy otherwise. I give him a hairball paste which does help as does brushing him, but nonetheless he vomits on a weekly basis without fail and always has.
In the process of buying a home with four beautiful cream carpets. In time we will replace these with hard floors but suspect that won't be for a good year. Can I please have your best tips for cleaning cat sick from carpets, especially for the times when he does it overnight so we don't see it until the morning by which time many hours have passed 
Thank you!
