Why does my cat with 3 fangs keep throwing up undigested food?

You may want to look at his teeth, especially his molars (cheek teeth). Mikkel may have a lot of tartar on his teeth and severe inflammation of his gums which then hurt when he eats dry food. If you see brown concrements on his teeth, then he should be seen by a veterinarian and get his teeth cleaned under anesthesia. There is no need to have a tooth ache, and the bacteria in tartar can actually cause heart and kidney problems.

Colby could be eating too quickly and vomiting secondary to that. Since you have changed his food already, I would try offering him a smaller amount and see if he can hold that down, then give him the rest.

It could be either one. I cannot tell you without examining him myself. I suggest you have the vet check his mouth for any signs of a dental issue. If that is not the problem, then it could be that the food is not agreeing with him and you should go back to the original diet.

Hi and thanks for posting! Yes, it is likely she is not chewing her food and is instead gulping her food. This could be caused by eating too quickly or may be due a dental problem. You may consider having Layla seen by her veterinarian to rule out a tooth issue as a cause. If a dental issue is ruled out, she may be eating too quickly and you may consider feeding smaller amounts more frequently or purchasing a slow feeder such as the one I have linked below. I hope this helps! https://www.google.com/shopping/product/16732113985708431597?lsf=seller:2653025,store:7688824421570661294&prds=oid:14280789946336739448&q=Pet+Co+cat+slow+feeder&hl=en&ei=gTQfW9mOMYuXjwSToL44&utm_source=google&utm_medium=cpc&lsft=gclid:EAIaIQobChMIwK_Mt47N2wIVgrrACh1RswVTEAQYBSABEgKKk_D_BwE

I'm sorry to hear Aries isn't doing well! Unfortunately, vomiting like this can be due to a number of things, which is why a vet visit is important. Issues such as a hairball or parasites can cause vomiting, along with functional issues that may be causing problems with digestion. Other issues can include food allergies (male cats tend to be allergic to ingredients such as fish or chicken in their foods) or even an issue with how often you are feeding Aries. Smaller meals more often can sometimes help vomiting if it's every morning, especially if Aries goes all night without any food. Offering a small meal right before bed (or a treat) can sometimes keep the stomach full enough to keep it from getting too empty and causing vomiting. However, since this has been prolonged and there are so many potential causes, a vet visit is always best.

Antibiotics can cause GI upset in cats, so it could be that Korben Dallas was eating less while he was on the antibiotics. Now that he's off the antibiotics, he's feeling better and eating much more quickly. That would be why he's throwing up all of his food. I would try to feed him smaller amounts more frequently to have him slow down his eating. If that doesn't help with the vomiting, I would take him into the vet for an exam, as he could have a medical illness causing the vomiting.

Marley is a very handsome boy! I'd have him checked out by a vet for a geriatric blood panel and urinalysis. In senior cats, there are medical conditions that can cause vomiting such as diabetes, hyperthyroidism, and kidney disease, and those tests I mentioned above can screen him for them. Should he have one of these, the vet can discuss treatment options with you. Please have him seen by a vet in the next few days. Best of luck.
