UK Cat Abscess Causes & Treatment After Injections

A cat abscess after injection UK is a relatively uncommon but concerning issue that can arise following vaccinations or other injections. While most cats tolerate immunisations without complications, some may develop localised infections or abscesses at the injection site.

Why Do Cats Get Abscesses After Vaccinations or Injections?

Abscesses occur when bacteria enter the skin, often through a puncture wound, and cause a localised infection filled with pus. In the case of injections, this can happen if bacteria are introduced during the procedure or if the cat’s immune system reacts adversely to the vaccine or medication.

• Contaminated needles or vaccines: Though rare, improper sterilisation can introduce bacteria.

• Immune response: Certain vaccines may trigger inflammation, leading to fluid accumulation and potential abscess formation.
• Underlying health conditions: Cats with weakened immune systems are more susceptible to infections.
