  • Some of the conditions that cause swollen toes may also cause other symptoms like fever, appetite loss, and lethargy
  • A thorough examination by a veterinarian is required to identify the underlying issue in cats with swollen toes
  • In addition to physical examination, diagnosis of the underlying condition may require biopsy, blood work, and diagnostic imaging

A closer look: Swollen Toes (Paw Pads) in Cats


Swelling of the toes is an uncommon finding in cats. If swelling of the toes is noticed with no other symptoms, non-urgent veterinary care is recommended.

Insect bites or stings can cause swelling, including in the toe pads, as well as serious allergic reactions. **Cats that are lethargic, having difficulty breathing, salivating excessively, vomiting, or have a blue tinge to the gums or tongue may be suffering from anaphylaxis and require emergency veterinary care. **

Possible causes


Swollen toes can be indicators of several different conditions.

Risk factors


Toe swelling can range from mild and barely noticeable to severe swelling that can impact mobility. One or more limbs may be affected. The severity of swelling and number of limbs affected do not necessarily indicate the severity of the underlying condition, so a thorough examination by a veterinarian is required.

Testing and diagnosis


A cat presenting with swollen paw pads usually requires some or all of the following diagnostics to determine the best course of action:

  • Physical examination: The veterinarian will focus on the feet and limbs, assessing pain and discomfort.
  • Blood work: The blood work may indicate whether the swelling is non-infectious or infectious and cal also be useful for identifying systemic underlying problems
  • Cytology: A needle is used to sample small numbers of cells from the paw pad for microscopic analysis
  • Biopsy: A tissue section from the paw pad is taken and submitted for evaluation
  • Allergy testing: May include intradermal testing, food trials or environmental management
  • Endocrine testing: To rule out endocrine disease which may cause swelling
  • Diagnostic imaging: X-rays or ultrasound may be used to examine the feet for abnormalities, such as tumors or abscesses

Treatment is dependent on the diagnosis. In some cases, the veterinarian may recommend analgesics and/or anti-inflammatories to make the cat more comfortable while diagnosis or treatment is in process.
