If your cat is limping after receiving a vaccine, you're not alone. This common reaction can be concerning for pet owners, but it's usually a temporary side effect of the vaccination process. Understanding why this happens and knowing when to seek veterinary care can help put your mind at ease while ensuring your cat's safety.
In this comprehensive guide, we'll explore the causes of post-vaccine limping, what's normal versus concerning, and how to care for your cat during recovery.
Common Vaccine Reactions in Cats
After vaccination, cats may experience several mild side effects as their immune system responds to the vaccine. These reactions typically occur within the first 24-48 hours and can include:
- Mild soreness at the injection site
- Temporary limping, especially if vaccinated in a leg
- General lethargy or decreased activity
- Slight fever
- Reduced appetite
These reactions are generally mild and self-limiting, resolving within a day or two without specific treatment.
Understanding Why Cats Limp After Vaccination
Limping following vaccination usually occurs due to localized inflammation at the injection site. Vaccines are typically administered in the legs or shoulders, and the resulting soreness can cause your cat to favor the affected limb temporarily.
The immune response triggered by the vaccine can also cause mild muscle soreness throughout the body, contributing to both limping and lethargy. This is actually a sign that your cat's immune system is responding appropriately to the vaccine.
