Why is my 10-month-old cat losing fur, has red skin, and bad breath?

It sounds like Sissy may have two issues going on. It's likely she is drooling and has bad breath related to dental infection and dental disease. She will need to see a veterinarian for a dental cleaning and to have infected teeth removed if dental disease is indeed causing the problem. Her skin issues could be related to flea issues so it's best to be sure she is on a quality flea preventative like Revolution or Advantage. If a flea Issue is not present Sissy will need to see a veterinarian to rule out issues like allergies or mites causing hair loss. Thanks for using Petco Pet Education Center, formerly Petcoach!

The odor may be a sign there is a skin infection from all the licking and biting. This can be due to an allergy either from fleas, food or something in the environment. Fleas are impossible to find on cats so it is best to just make sure she is on prevention. You can change to a hypoallergenic diet for food allergies. As far as environmental allergies, they are impossible to control, so I would have your vet check her to clear the infection if needed and see what medications can be given to help with the allergies.

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.

I don't see any hard evidence of fleas although i can't rule it out and would recommend treating for them anyway, this looks more like either a fungal, bacterial infection or an allergic reaction. i would not recommend using this shampoo prior to getting this condition diagnosed by your vet.

Fleas cannot be the cause for the breathing and other general symptoms, the scabs over the neck could be caused by the fleas. unfortunately this is not all, he seems to be suffering from an infection that is causing those symptoms, you will need to take him to the vet ASAP in order to get it checked and treated.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Billie! How old is Billie? I wonder if Billie is young if he has a food allergy. The most common cause of vomiting in cats is a food intolerance. I would avoid a chicken based diet and get him on venison, all fish or beef. Billie could also be pulling his hair out do to skin allergies from food. Other causes of pulling out hair are fleas or stress. If Billie is old and is drinking more then I recommend full blood work. Causes of increased thirst are: kidney disease, diabetes, hyperthyroidism (overactive thyroid), liver disease and cancer. Causes of bad breath are dental disease, kidney disease and sometime diabetes. I think the best thing for Billie is to see a Veterinarian. I hope this helps and I wish Billie the best!

Poor Freckle! Without seeing a photo or completing a physical exam, it’s hard to know why this is happening. Pets can get red marks on the skin due to flea bites, environmental allergy, food allergy, contact allergy or hyperthyroidism. Red marks could also indicate bruising which is much more serious and significant. Bruising indicates platelet abnormalities and this can be fatal without treatment. Since you are noticing the issue is so widespread, I recommend to have him examined by his veterinarian today ideally. It’s always best to play it safe. Best of luck and please feel free to post any additional questions.
