The cat will be fine after eating mecobalamin.

Mecobalamin is a vitamin B 12, which plays an important role in the health of cats. Vitamin B 12 can promote the production of red blood cells and maintain the normal function of nervous system. Cats who eat food containing mecobalamin may get better to some extent if they lack vitamin B 12. This is mainly reflected in the following aspects:

1. Eliminating anemia symptoms: Vitamin B 12 can stimulate the production of red blood cells, so cats may be anemic in the absence of vitamin B 12, and the symptoms of anemia may be alleviated after eating mecobalamin.

2. Improve nervous system problems: Vitamin B 12 is very important for the functional maintenance of the nervous system, so cats may show some neurological symptoms when lacking vitamin B 12, such as unstable walking and convulsions. Eating mecobalamin can improve these problems.
