Why are my cat's gums and tongue purple/blue? Is it serious?

White gums in any animal is concerning as it can be a sign of shock or anemia. Based on your attached photos, I would not be alarmed about the color of the gums. They are not pale, they are an adequate pink color. Unless you notice other changes such as weakness or lethargy or vomiting, then I would not worry and just monitor for further changes.

It's possible the pink coloration is gingivitis or it could also indicate an infection. The not eating could be related to dental pain but it could also be related to something else. I recommend to have Milo examined by the veterinarian. A physical exam is needed to begin the process of figuring out what's wrong and fixing it. Here is a link about dental care and dental disease just in case: https://www.petcoach.co/article/a-comprehensive-dental-care-program-for-your-cat/ I hope this helps and please feel free to post any additional questions.

What I see in the picture is a change in color where the gums meet the hair line. This is something I see just as cats age. Sometimes in orange cats the skin will become black in pigmentation. Other times you will see a blue color. I would just continue to monitor it for now. If it gets bigger to you can take Schmidt to the vet for a quick check but I do not think it was related to the dental

If her gums and tongue turned blue (cyanosis aka cyanotic), this is a sign of not getting enough oxygen. This can come from a heart problem, a tracheal issue like tracheal collapse, a severe allergic reaction, poor pulmonary perfusion (pneumonia, cancer, fluid around the lungs, etc) and much more. I would strongly recommend to take her to the vet for an exam to see if they can figure out what caused her to be cyanotic and hopefully prevent it from happening again. Lack of oxygen can be fatal if not immediately treated. I hope this helps!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! For a kitten Noushmc's age the gums should be a light pink and the tongue should be pink (darker shade than the gums). If the gums are white that is an emergency and indicates a severe anemia. I hope this helps and have a great day!

Cat gums can normally appear more pale than you would expect on a dog. Also, pale mucous membranes is not a great indicator of anemia, because the color can be influenced by other factors such as blood pressure and environmental temperature. Pictures are not a great way to visualize colors, but this does not seem unusually pale to me. If you feel like you are noticing a drastic change in the color, then it is possible that something is off in her body, but not likely if she is otherwise acting normal. The conditions that cause pale mucous membranes would cause other clinical signs such as weight loss, decrease in appetite, and/or decrease in activity. I think you have little to worry about right now, but it's difficult for me to tell for sure without examining her. The best way to make sure she is healthy is to schedule a wellness exam with your vet. They will be able to help you further with this concern. I hope that helps and all is well with Kitty.

Hi! So sorry to hear that Paris is not feeling well. It sounds like Paris is anemic based on the color of her gums and the fact that she does not feel well which means that she is clinically affected. I recommend that you have Paris evaluated by a veterinarian as soon as possible to figure out what is wrong and start therapy for it. At the very least, she could have bloodwork done to see if she truly is anemic and go from there. Keeping my fingers crossed that evrything goes well!!
