(4 Packages) VetriScience Laboratories - Composure Feline, 120 Bite-Sized Chews Total (30 Per Pack). 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.
