Carcinoembryonic antigen (CEA) describes a set of highly-related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth. Consequently, CEA is usually present at very low levels in the blood of healthy adults (about 2–4 ng/mL). [2]
Aging in cats is the process by which cats change over the course of their natural lifespans. The normal lifespan of domestic cats is in the range of 13 to 20 years. As cats senesce, they undergo predictable changes in health and behavior. Dental disease and loss of olfaction are common as cats age, affecting eating habits.
References range may vary with age, sex, race, pregnancy, [10] diet, use of prescribed or herbal drugs and stress.

Carcinoembryonic antigen-related cell adhesion molecule 1 (biliary glycoprotein) (CEACAM1) also known as CD66a (Cluster of Differentiation 66a), is a human glycoprotein, and a member of the carcinoembryonic antigen (CEA) gene family.
Evidence suggests that middle-aged cats and dogs, especially those between the ages of 5 and 10, may be at an increased risk of obesity. [11] This is supported by studies showing that as cats age from 2 years to approximately 11.5 years of age their energy requirements decrease. [12]

Cancer in cats is the leading cause of death among cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body.
CA 242 is a tumor marker for sialylated Lewis carbohydrates associated with adenocarcinomas and e-selectin-mediated metastatic risk. [1] [2] [3] It is commonly tested along with CEA, CA19-9, and CA242 for detecting pancreatic cancer. [4]
