Cats become depressed after being vaccinated and usually recover after one to two days. If the cat still shows signs of lethargy and loss of appetite after two days, the owner needs to consult a pet doctor in time or take the cat to a pet hospital for examination. Usually cats will develop allergies, vomiting, diarrhea, lethargy, red skin, shock, etc. after being vaccinated. Therefore, they should be observed for half an hour after being vaccinated before leaving.

What should be paid attention to when vaccinating cats:

1. Cats must be vaccinated after they are two months old, usually after 9 weeks. Because kittens that are too young still have antibodies obtained from breast milk, the vaccine injected at this time will interact with the antibodies, making the injected vaccine ineffective.

2. Do not vaccinate the cat immediately when you first bring it home. The cat should be allowed to adapt for a period of time before being vaccinated to avoid stress reactions.

3. After being injected with the vaccine, as the immune system begins to react, cats may have fever, poor spirits, loss of appetite, lethargy, etc. These are normal reactions and usually resolve on their own in 1-2 days. recover. If it does not return to normal after 2 days, consult your pet doctor promptly.
