LickiMats were invented by an Australian company to help improve the health and mental well-being of cats and dogs. More than 2 million LickiMats have been sold worldwide. LickiMats stimulate the tongue to increase saliva that in turn leads to healthier teeth and gums. Tongue scraping also minimises undigested food particles and odor-causing bacteria. By engaging pets over a long period of time while delivering only small portions of their favourite treat, they promote calm behaviour while your pet is home alone, or during stressful times. LickiMats are made from human grade rubber (TPR). They contain no silicone, or toxic substances. They are microwave proof, dishwasher safe and freezer friendly. LickiMat Soother Tuff Pro is recommended by professional dog trainers. It is 20cm x 20cm and has a pimpled surface that is particularly suitable for spreadable treats such as yogurt, peanut butter, broth, etc. Chew resistant and ideal for teething puppies, or dogs that will chew anything.
