Although vomiting is not uncommon in cats because of hairballs, if your cat vomits after eating on a daily basis, you should see a veterinarian to check for a meat allergy. Some other signs of meat allergy include:
- Scratching more than usual
- Itchy ears, head, and neck
- Chewing on paws
- Bald spots cause by chewing on skin
- Redness of the skin
- Raised red lesions anywhere on the body
- Dry and flaky skin
- Crusty lesions on skin
- Vomiting
- Diarrhea
- Red ears or ear infections
Types
There are four types of allergies, which include:
Type I Immediate Hypersensitivity
This is an IgE response that includes smooth muscle and mast cell vascular responses. This type is the basic allergy that occurs immediately after eating and causes itching and vomiting. This can be dangerous and can instigate a life-threatening condition called anaphylaxis that causes throat inflammation and suffocation. However, this is very rare in cats.
Type II Antibody Mediated Hypersensitivity
This occurs when the immune system reacts to a certain food and causes intestinal upset, extreme itching, and inflammation. This is a more aggravating type of allergy commonly called autoimmunity.
Type III Immune Complex Hypersensitivity
This type is an overreaction of the immune system that can create problems in major organs in the body such as with rheumatoid arthritis and lupus.
Type IV Delayed Hypersensitivity
This type does not appear until at least 24 hours after exposure and is considered to be genetic.
