My cat has stomach lumps, vomiting, and rapid weight loss. What to do?

Given his symptoms, he should be physically examined by your veterinarian. A fine needle aspirate can be done in the clinic to collect samples for pathology. This may determine if the bump is something that needs to be addressed or simply monitored. Your vet may recommend lab work (CBC, chemistry panel, urinalysis) to diagnose the underlying cause for the vomiting and weight loss. These symptoms have multiple causes. Abdominal x-rays may also be recommended. Supportive care (IV or subcutaneous fluids, antibiotics, anti-emetics, etc.) can be administered as indicated.

I would not pull it off yourself. These may not be related to the other signs. Your vet needs to examine him to see if blood work is needed for the decrease in appetite then can address the skin troubles at the same time

It could be a severe skin infection or an acute allergic reaction. I would recommend a vet check up so that she can get some treatment on board. These reactions can be quite painful and cause itchiness. Vomiting could also be a sign of allergic reaction, leave water down but no food until you see your vet. I would arrange a visit this morning, if possible.

I'm wondering if your cat is spayed or not. If your cat isn't spayed, she could have a mammary tumor. In cats, 90% of these are malignant. She does have to see a vet for this problem, as a malignant tumor could also be causing her to vomit. Please take her into a vet now. Best of luck.

I hate to hear that Spirit is so sick. If you are feeling a lump in her stomach, it could mean she has swollen something she shouldn't have an it is causing an obstruction. This is a serious condition that is fatal unless the obstruction is removed (usually this requires surgery). Pets can vomit due to many other reasons including infection, poisoning or parasites. Spirit sounds like she is very sick and I am very concerned if the lump you are feeling is real. I recommend to take her to an emergency veterinary clinic if one is available. If you cannot get her to an emergency clinic, fast her from food but make sure she is drinking small amounts of water frequently. Unfortunately, there is not anything else you can do at home. Get her into the veterinarian's office as soon as you can. She will x-rays to look for a foreign object in her abdomen. I hope every thing turns out ok and please feel free to post any additional questions.

I'm sorry to hear that your cat isn't doing terribly well. There are several different possibilities here. One is that his weight loss is completely unrelated to the masses. As cats get older, they're more likely to develop conditions like hyperthyroidism or kidney disease, which can lead to weight loss. While neither of these conditions can be "cured," both can be managed to some degree with certain medications or diet. The other possibility is, as you mentioned, that these masses could be cancerous. I completely understand not wanting to pursue extensive treatment for cancer, but before making the assumption that it is cancer, I'd try to get some more information. For starters, I think it's perfectly reasonable to take your cat to the vet for an exam and some bloodwork to check his organ function. There's a chance that your vet may find something that's not terribly difficult to manage, but you don't know unless you look. I would expect that your vet would recommend trying to diagnose the masses in order to be thorough, but if you are clear that you don't want to look into them further, it shouldn't be an issue. At the end of the day, you own your cat and are responsible for making choices for him. Your vet's job is to present those choices to you and help you to find the approach that works best for you and your cat. I hope this helps and that everything goes well.

Oh no, poor MK! This sounds very serious these lumps have slowly been growing, and I would be very concerned that these lump are malignant tumors. It's also concerning that it has opened up to a wound on top. Given that this is spread and opening up, the best thing to do it have MK seen by a vet. I too am worried about infection and the seriousness of these, so it would be best to have her seen by a vet right away for this. Please take her into the vet first thing in the morning.
