Why is my cat not eating, losing weight, bad breath, lip spot?

Squiggles need to see a vet. If he has lost that much weight my guess is he either has diabetes or kidney disease. He could also have a serious mouth/dental infection or even hepatic lipidosis. I'm sorry you think vets are expensive but there is a lot of overhead involved with running a vet clinic. The staff has to be paid, the utilities, all the medications, supplies and equipment. It is your responsibility to get him care when he is sick. Letting him suffer because of financial constraints is really not a good option. Not everything can be fixed at home. So, please get him evaluated by a vet and then you can go from there. If he has a severe disease and you cannot afford treatment then it would be best to humanely euthanize him.

Your cat needs to see his veterinarian ASAP. It is possible that your cat has a tooth abscess, severe periodontal disease, something lodged inside the mouth, an injury, or an oral tumor. Regardless of cause, this is a serious medical condition since it is preventing him from eating and drinking normally. Your cat is at risk of becoming dehydrated and developing a condition called hepatic liposis, which can lead to liver failure. Even going 24 hours without food can cause changes in liver functioning.

Thanks for using Petco Pet Education Center, formerly Petcoach! Losing weight despite having a good appetite is a classic sign seen with hyperthyroidism. This is just one possibility among other conditions. I recommend you check in with a veterinarian for further assessment and treatment. They would be able to check for this and proceed with therapy accordingly. Best of luck!

Thank you for submitting your question regarding Sam. I recommend that he sees an emergency veterinarian today. He needs to be examined. If there is a smell coming from his mouth, I worry that he has a wound. If he is painful, then he will not open his mouth. There are also other causes of not being able to use the mouth properly such as infectious and inflammatory conditions. The veterinarian will examine him and may recommend some testing. Based on these results, treatment can be started to help him feel better. I worry that he will become dehydrated from not eating and drinking properly. This may need to be addressed as well. I hope this information helps!

Mingming really needs to see a vet soon. It looks pretty bad, and could be caused by a fractured jaw, severely infected teeth, or cancer. All of these issues would be treated completely differently. She would also benefit from some pain medications. Since we don't know what is the cause, it is difficult to recommend a treatment, and it is illegal for us to prescribe medications.

Based upon the lack of response to treatment, it’s likely Kuskus has an internal disease like renal disease or hyperthyroidism but many many conditions will cause these clinical signs. Dental disease is also possible. At this point, he needs to be examined by the veterinarian and needs bloodwork to check his organ enzyme levels. Have him examined today before he gets worse. I hope this helps and please feel free to post any additional questions.

He may have an injury or something stuck in his mouth that makes him painful and reluctant to eat. I strongly recommend getting him seen by a vet right away, even though he's feeling better. There may still be something that can be corrected to make him feel better, and if he has swallowed something he shouldn't have or injured his mouth by chewing something he may need veterinary care in order to heal completely.
