What Heart Rate Is Normal for a Cat? Vet-Reviewed Advice

Updated on
If you are cuddling with your cat and you feel their heart beating fast or slow, you may wonder if something is wrong. After all, what is a normal heart rate for a cat, and how do you know that they are healthy?
The normal heart rate for a cat is between 140 and 220 beats per minute (bpm). A healthy cat’s heart rate should be regular and consistent, with no skipping or extra beats. However, there are some instances in which a cat may have either a low or high heart rate, as well as an irregular one. Let’s learn more about a cat’s normal heart rate, and when you should be concerned.
Low Heart Rate in Cats
In cats, a low heart rate (or bradycardia) is defined as anything below the normal range of 140 to 220 bpm. This can happen due to certain medical conditions such as hypothyroidism, congestive heart failure, or even exposure to certain medications. Signs that you may notice if your cat has a low heart rate include lethargy, weakness, and breathing difficulties.
High Heart Rate in Cats
In cats, a high heart rate (or tachycardia) is defined as anything above the normal range of 140 to 220 bpm. This can be caused by certain medical conditions such as hyperthyroidism, fever, or even exposure to certain medications. Signs that you may notice if your cat has a high heart rate include restlessness, panting, and an increased respiratory rate.
Irregular Heart Rate in Cats
An irregular heartbeat (or arrhythmia) is when your cat’s normal heart rhythm becomes inconsistent or unpredictable. This can happen due to certain medical conditions such as heartworm disease or cardiomyopathy. Signs that you may notice if your cat has an irregular heart rate include fainting, weakness, and difficulty breathing.
Signs You Should See Your Veterinarian
If you notice any changes in your cat’s behavior or physical condition, it’s important to see your veterinarian as soon as possible. Some signs that might indicate a problem with your cat’s heart include:
- Decreased energy levels
- Difficulty breathing
- Rapid heartbeat
- Weakness or collapse
- Loss of appetite
- Coughing or wheezing
Your veterinarian will be able to perform a physical examination to determine the cause and provide the necessary treatment or lifestyle changes to help your cat live a healthier life.
The Top 10 Types of Feline Heart Disease Explained
1. Cardiomyopathy
This is a type of heart disease in which the heart muscle becomes weak or unable to contract properly.
Cause: | Unknown |
Signs: | Lethargy, coughing, difficulty breathing |
Prevention: | Regular veterinary check-ups |
2. Congestive Heart Failure
This is a type of heart disease in which the heart cannot pump enough blood to the body and fluids build up in different parts of the body.
Cause: | Congenital defects, high blood pressure, heartworm disease |
Signs: | Lethargy, coughing, difficulty breathing, swollen belly and legs |
Prevention: | Regular veterinary check-ups |
3. Pericardial Disease
This is a type of heart disease in which fluid accumulates inside the sac surrounding the heart.
Cause: | Unknown |
Signs: | Restlessness, difficulty breathing, chest pain or discomfort |
Prevention: | Regular veterinary check-ups |
4. Arrhythmias/Electrocardiogram Abnormalities (ECG)
This is a type of heart disease in which electrical signals that control your cat’s heart rate become irregular, making the heart beat too fast or too slow.
Cause: | Unknown |
Signs: | Fainting, weakness, difficulty breathing |
Prevention: | Regular veterinary check-ups |
5. Hypertrophic Cardiomyopathy (HCM)
This is a type of heart disease in which the walls of the left ventricle become thickened due to an increase in muscle fibers.
Cause: | Unknown |
Signs: | Exercise intolerance, difficulty breathing, chest pain or discomfort, lethargy |
Prevention: | Regular veterinary check-ups |
6. Valvular Disease
This is a type of heart disease where one or more valves within the heart are not functioning properly.
Cause: | Unknown |
Signs: | Weakness, difficulty breathing, chest pain, or discomfort |
Prevention: | Regular veterinary check-ups |
7. Pulmonic Stenosis
This is a type of heart disease caused by the narrowing of the pulmonary valve which prevents blood from flowing normally between the left ventricle and the lungs.
Cause: | Congenital defect or unknown |
Signs: | Rapid breathing, exercise intolerance |
Prevention: | Regular veterinary check-ups |
8. Patent Ductus Arteriosus (PDA)
This is a type of heart disease in which an opening remains in the fetal circulatory system that should close after birth. It can cause a high pressure in the lungs and heart, causing congestive heart failure.
Cause: | Congenital defect |
Signs: | Rapid breathing, lethargy |
Prevention: | Regular veterinary check-ups |
9. Aortic Stenosis
This is a type of heart disease in which the aortic valve does not properly open and close, causing an obstruction in blood flow from the left ventricle to the aorta.
Cause: | Congenital defect or unknown |
Signs: | Weakness, fainting, difficulty breathing |
Prevention: | Regular veterinary check-ups |
10. Degenerative Valve Disease (DVD)
This is a type of heart disease caused by the deterioration of one or more valves in the heart. It’s uncommon in cats.
Cause: | Unknown |
Signs: | Lethargy, difficulty breathing, chest pain or discomfort |
Prevention: | Regular veterinary check-ups |
Adopting a Heart-Healthy Lifestyle for Your Cat
