Composure™ chews for cats are a calming supplement designed to promote relaxation during stressful situations. Examples: Your cat is headed to the vet. You had a new baby. You are having guests over for the holidays. You heard there’s about to be a thunderstorm. Whenever your cat is stressed, calming chews offer positive support. Three main ingredients work together to support relaxation without affecting your cat’s energy levels or personality. The Colostrum Calming Complex™ BiopeptideBlend supports stress reduction and cognitive function; L-Theanine helps the body produce other amino acids to bring specific neurotransmitters back into balance; and B vitamins (thiamine) affect the central nervous system to help calm anxious animals. No herbals used.
