My cat has a black mouth growth, can't eat, and is losing weight.

Without examining your cat or at least seeing some photos it is very difficult for me to comment. The best I can tell you is that he needs to see a vet so he can be examined in person. He may have a seriously infected tooth or even a tumor in his mouth cavity. Both things can cause the sign you describe. He cannot be left in this condition without eating and losing weight. It sounds like he is in pain so he needs to see a vet right away. I would not wait to get him examined. This is an emergency in my opinion.

Unfortunately, in this area I would be concerned that this is some type of cancerous growth.I would recommend an immediate vet visit - your vet can take a sample of the lump and tell you what it is. Based on that diagnosis a treatment plan can be developed.

Ariel sounds very sick, and I would consider this a medical emergency. She could have a systemic illness, infection, or injury causing her problems. She needs to see a vet now. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

It could be Blackie has a respiratory infection affecting her ability to meow. If she's congested, she won't eat as much. Cats like to smell their food, and if they can't smell it, they won't eat. Have her seen by a vet today. Best of luck.

I recommend taking Princess to a vet. As cats age they can develop multiple different systemic diseases which they can develop these symptoms. The most common being diabetes, kidney disease and hyperthyroidism. Your vet can run blood work to see if she has any of these and discuss treatment with you.

Oh dear! Poor Prince. I'm afraid these are very concerning symptoms. This does sound like a life-threatening problem, so I would recommend taking him to an emergency vet tonight to be seen. If this isn't possible, then he needs to see your regular veterinarian first thing in the morning. He will likely need blood work and x-rays to help diagnose the problem and see what can be done to help.

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.
