Hi everyone! Just had a quick question... Is dry food really necessary? My cat has been coughing up hairballs once a week and I'm thinking about just eliminating dry food and giving her wet. I give her a full can of wet food everyday (3 oz) and a little under a 1/4 scoop of dry. The vet was saying she could possibly have a food allergy, but doesn't really show the symptoms (we give her mainly chicken). I've ordered laxatone and I'm hoping it helps with hairballs, but was wondering if an all wet food diet would help as well. Also, is it a myth that dry food helps with cats teeth?
