My cats used to stain the carpet when coughing up hairballs and I found out through a vet that it was because the cat food I was giving them had artificial coloring in it. I am very careful to read the package before I buy any treats or food. I also brush them a lot but my one cat will still vomit occasaionally – but it doesn’t stain the carpet…Hope this helps you. -Ellen
