How can a thunder shirt help calm anxious cats during storms or loud noises?

A thunder shirt can help calm anxious cats during storms or loud noises by providing gentle, constant pressure that can help reduce their anxiety and make them feel more secure. The pressure from the shirt can have a calming effect on the cat's nervous system, similar to the way swaddling a baby can help them feel safe and secure. This can help the cat feel more relaxed and less stressed during stressful situations like storms or loud noises.
