Thanks for your comment, Rich. Upping the amount can cause stomach and intestinal distress just like in humans so you want to make sure he is not getting too much. In terms of a cure, it is probably best to work with a holistic veterinarian for the best natural treatment. We can’t give medical advice as we are not vets here. What I can tell you is that you should ensure any toxins in your cat’s environment are removed to help increase the odds of if going away. Don’t allow your cat to be around smoke from cigarettes, room sprays and air fresheners, switch to pet-safe home cleaners, and be sure he/she has access to fresh air and clean water. If your cat is overweight and inactive, encourage some playtime. Obesity in cats increases cancer risk and can make cancers worse. Being physically active stimulates the lymphatic system in your cat the same way it does in us humans, which can help big time.
