Cats/Cat has smelly drool in sleep


Sometimes when my cat sleeps, she drools, and I find it adorable. But today, I noticed she was leaving massive puddles of drool that just smelled absolutely awful, almost body odor-like, which the smell would fill the room. And this was only after about 15 minutes of sleeping. She seems to be acting a bit off today, very lethargic and out of it. My friend says it might be just a bad hairball, which is what I'm hoping for, because she is a very old cat, and up until today, seemed to be in the best health I've ever seen in a cat this old.


There are a number of things that can cause foul smelling drool including dental disease, kidney/liver issues... I would suggest having your kitty checked out by a veterinarian just to rule out anything more serious. Typically hairballs result in vomiting, not foul breath/stinky drool. If you have any further questions or concerns, please don't hesitate to contact me again at any time - I'm more than happy to help in any way that I can.

Kind regards,

I am the proud guardian of 5 mixed breed cats ranging from 12 weeks to 13 years old and one purebred ragdoll. I have 20+ years experience working with mixed breed cats from a variety of different situations. I have fostered cats/kittens with special needs/behavioral issues. I have rescued/rehabilitated/re-homed a variety of stray/abused cats. I can offer advice on managing feral cat colonies, rehabilitating strays and finding them forever homes. I can help you to determine whether a cat is stray or feral, there IS a significant difference. Improperly introducing a new cat/kitten can result in aggression between newly introduced cats because cats are territorial by nature and they don't like sudden changes in their environment. To learn more about a peaceful way to introduce a new cat into a home with other cats please check out my previous answers on this subject. Proper nutrition for cats can be confusing, I recommend checking out which was created by a veterinarian (Dr. Lisa Pierson) who takes a common sense approach to explaining feline nutrition. Cat behavior and instincts are different from those of humans, I can help you understand your cat's needs so that you can meet them adequately and have a balanced, psychologically and physically sound kitty. Cats vary in personality, energy level and intelligence, different approaches may be required to achieve results in terms of training and interaction with your feline companion. An intelligent, high energy cat must be kept busy or they will make their own fun. I am NOT a licensed veterinarian and I can't offer medical advice. If your cat is ill/injured my advice is always the same: get prompt medical treatment provided by a veterinarian. If finances are an issue I will try to find resources in your area that can help with medical costs or make other choices to ensure the welfare of your cat.


I have fostered feral and stray cats, rehabilitated and homed cats that many people recommended euthanasia for. I am willing to make an effort to do the research and ask questions because I care enough to find solutions to behavioral problems rather than giving up. I have an interest in the use of alternative therapies to help provide the best possible care for all cats and I can say in all honesty that I've seen some incredible things happen for some incredible cats and their human caregivers when the right alternative therapeutic modality is used by a qualified veterinarian with expertise and experience in the field.

I've earned my diploma as a veterinary assistant with honors.
