My Cat Got the Second FVRCP Shot and Is Now in Heat; What About the Third Shot, and If Pregnant?

Per your cat’s vaccination schedule, the third shot is due and can be given as long as eating, defecation, and energy are normal, because being in heat does not affect vaccination. After the shot, watch the cat closely, boost its immunity, avoid baths and outings, and do not let it mate or go outside to breed accidentally. If pregnancy occurs, schedule regular checkups to assess the cat’s health and your wishes; if allowed, natural birth is fine, but if you do not want kittens, an abortion after detection is an option, though it harms the cat’s body. The owner should supervise during heat and have the cat spayed at the proper age.
