Question:
What is the average size of a cat's heart?


Replies:
Hi Rebecca,

That is a good question. The average weight of a cat's heart is about 2.5-3 grams, with male cats having slightly heavier hearts than females. The larger the cat the larger the heart will be. In other words, a 20 pound male Maine coon cat will have a larger and heavier heart than a 10 pound female calico. To give you an idea of how big a 2.5-3 gram heart is, think about something the size of a walnut in its shell. I hope this answers your question. Regards,
