Thumps

Thumps is a term used to describe a rhythmic contraction of the diaphragm muscle in animals such as horses and rabbits that can cause them to make a noticeable bouncing or "thumping" noise. The diaphragm muscle helps animals breathe by contracting and pulling air into their lungs, but when it contracts in a rhythmic pattern, it can cause the thumping noise.

Some common causes of thumps in animals are stress, fatigue, excitement, or digestive issues. Thumps may also be a symptom of more serious health problems, such as dehydration or heart disease, so it's important to monitor an animal if they are experiencing thumps and consult a veterinarian if necessary.

In summary, thumps is a condition where an animal's diaphragm muscle contracts rhythmically, causing a bouncing or thumping noise, which can be a symptom of various health issues.
