Yes, dental treats for cats work, but you might need to rein in your expectations. Dental cat treats aren't meant to be the only form of dental care for your pet but rather an extra boost to oral hygiene between brushings. It’s a bit like us humans flossing or using mouthwash — it's good for our dental health, but it isn't all we need to do to keep our teeth and gums healthy. If you absolutely can't manage to brush your cat's teeth, your feline friend may need a professional cleaning down the line.
