Is a hard, protruding bone on my cat's chest between her legs normal?

You might be feeling the manubrium, which is the top of the sternum, in this area. A little higher up are the bones of the larynx and hyoid apparatus. https://www.k-state.edu/organismic/cat_skeleton.htm

Hi there. Without being able to see the bump and palpate it, I can't really say if this is normal or not. It may be that you're feeling a normal anatomical structure, but it could also be a growth or tumor, a hernia, or some other problem that needs medical attention. I would recommend taking Bumblebee to the vet for an exam. He/she can palpate the bump to help determine what it might be, and will advise you from there on whether anything needs to be done.

That looks like it may be a cutaneous horn-type growth. Sometimes, they can dry up and fall off on their own, however, they can also sometimes be cancerous. With any new bump, it's always best to confirm in person with your vet as it is not always possible to determine what a growth is by looks alone. Your vet can take a sample of the growth to determine the cell type, or safely remove it if it is bothersome or itchy for Tiger. Until you get to Tiger's next vet checkup, keep an eye on the area for any signs of something more serious ongoing such as rapid changes in size, redness, irritation, irregular shape changes, pus, or discharge. These are all signs that the growth should be seen ASAP instead.

Hello. It is impossible to say exactly what might be going on, but we should rule out the possibility of a bruised rib or small fracture. Your veterinarian may need to clip some hair down to the skin to see what things look like. It is good that everything else is well with her so it does not sound like there is anything serious. But if your vet suggests an x-ray, this might be a good idea. Thanks for using Petco Pet Education Center, formerly Petcoach.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! It could be a small cyst (non cancerous growth) from epidermal origin, or potentially a small abscess that has not yet reached the point of rupture from a sting or bite. If it is possible I would suggest clipping the hair short to get a better look. If you can get a picture, this would help us to better help you out. Likely Freya will need to see a vet for either a drainage of this or a removal if the mass becomes bothersome. Antibiotics will be warranted if the mass ends up being an abscess that is currently brewing under the skin. I hope this helps! Please resubmit if you can get some photos! We'd love to be as accurate as possible.
