My 2-month-old kitten has bad breath. Is it due to losing baby teeth?

At this age the bad breath might be because of teething, which occurs until the age of around 5 months of age, after that if the bad breath remains it's probably due to gum disease, which is very common in cats, in most cases it doesn't bother the cat and thus does not require treatment.

Halitosis (bad breath) in a kitten can be caused by oral infections such as gingivitis (inflammation of the gums) or feline stomatitis (inflammation of the oral mucous membranes at the back of the mouth). Teething can also cause bad breath. Another cause that is harmless is certain food like canned soft food can sometimes cause the kitten bad breath, for example, smoked oysters or canned tuna. Other causes such as kidney/liver disease and diabetes are less commonly found in kittens. I would suggest to take the kitten to your vet to examine the mouth and identify the cause.

The best way to help this problem is to brush his teeth every day. The stimulation of the gums that happens when brushing will help with the inflammation. You must use a toothpaste made for animals. I don't know what products you have available to you in Tunisia so it's hard for me to make any recommendations.

Bad breath has nothing to do with worms. It’s due to tartar buildup on the teeth and bacteria in the mouth. Just like if you never brushed your teeth you would have bad breath too. The best thing you can do is start brushing his teeth daily. You can watch a YouTube video on how to do this properly or you can consult with your local veterinarian to get instructions on how to brush his teeth.

You need to take her to the vet ASAP, she is probably suffering from a gum/teeth disease which is very common in cats, treatment varies according to the severity of the condition but this must be dealt with urgently.

I am sorry to hear about your concerns!!! It sounds like your kitten is of the age when it is getting its final adult teeth (usually 6-7 months) so it is possible your kitty is just losing her baby teeth. When kittens are teething sometimes they do have a bad breath/odor while they are teething. When the teeth fall out we can have some bleeding at the gums as well. If the bleeding was prolonged, your kitty is having trouble eating or is lethargic or pawing at her mouth, I would recommend an exam by the vet to look at the oral cavity to ensure there aren't any signs of infection, a foreign body stuck in the gums, or ulceration. Best of luck to you and Nala!

Muffins might be suffering from gingivitis, but because of his young age i would recommend to wait at least 2-3 months before you get it checked, the reason for that is that he is probably still teething at the moment and his new set of permanent teeth are just setting up, this might be the cause of the smell.
