By Dr Duncan Houston, BVSc
🔍 What Are Cat Abscesses?
An abscess is a painful pocket of pus under the skin or inside the body, caused by bacteria invading through wounds—most often from cat fights. Pus forms as white blood cells fight infection :contentReference[oaicite:3]{index=3}.
⚠️ Common Causes
- Bite wounds—especially in outdoor or intact male cats :contentReference[oaicite:4]{index=4}
- Scratches, splinters, foreign body trauma :contentReference[oaicite:5]{index=5}
- Tooth root abscesses—swollen cheeks, drooling, difficulty eating :contentReference[oaicite:6]{index=6}
- Anal gland or ear infections :contentReference[oaicite:7]{index=7}
- Internal abscesses in lungs, liver, brain—rare but serious :contentReference[oaicite:8]{index=8}
🚩 Signs to Look For
- Swelling, redness, tenderness under skin :contentReference[oaicite:9]{index=9}
- Discharge—pus, sometimes bloody, foul-smelling :contentReference[oaicite:10]{index=10}
- Lethargy, fever, poor appetite :contentReference[oaicite:11]{index=11}
- Limping if limb affected :contentReference[oaicite:12]{index=12}
- Facial swelling, drooling, difficulty eating (dental abscess) :contentReference[oaicite:13]{index=13}
🔬 How Vets Diagnose Abscesses
- Physical exam—feel for swelling, warmth, signs of pain :contentReference[oaicite:14]{index=14}
- Fine-needle aspiration or fluid sampling for cytology/culture :contentReference[oaicite:15]{index=15}
- Blood work if systemic signs are present :contentReference[oaicite:16]{index=16}
- Dental X-rays for suspected tooth root abscess :contentReference[oaicite:17]{index=17}
- Imaging (ultrasound, X-ray) for deep or internal abscesses :contentReference[oaicite:18]{index=18}
💊 Treatment Approaches
- Drainage & Cleaning: Vet lances, flushes, may insert drain; sedation often required :contentReference[oaicite:19]{index=19}
- Antibiotics: Often Clavamox or Convenia; culture guides choice as needed :contentReference[oaicite:20]{index=20}
- Pain Management: Onsior or similar NSAIDs as prescribed :contentReference[oaicite:21]{index=21}
- Special Cases: Tooth abscesses → extraction under anesthesia :contentReference[oaicite:22]{index=22}
- Hospitalization: For deep, infected, or febrile cats :contentReference[oaicite:23]{index=23}
🏡 Home Care & Recovery
- Keep cat indoors—avoid reinjury and contamination :contentReference[oaicite:24]{index=24}
- Apply warm, sterile compresses if recommended :contentReference[oaicite:25]{index=25}
- Maintain open drainage—clean twice daily unless sutured :contentReference[oaicite:26]{index=26}
- Use an Elizabethan collar to prevent licking :contentReference[oaicite:27]{index=27}
- Follow antibiotic and pain management regimen fully
- Recheck in 5–7 days or sooner if no improvement
📅 Prognosis & Follow-Up
Most abscesses heal within 1–2 weeks with proper care :contentReference[oaicite:28]{index=28}. Deeper abscesses or those linked to immune suppression (e.g., FIV/FeLV) may need longer care and monitoring :contentReference[oaicite:29]{index=29}.
🛡️ Prevention Tips
- Keep cats indoors to reduce fights and injuries :contentReference[oaicite:30]{index=30}
- Spay/neuter to lower territorial aggression :contentReference[oaicite:31]{index=31}
- Maintain dental health: routine cleanings prevent tooth abscesses :contentReference[oaicite:32]{index=32}
- Inspect wounds early—seek vet care within 24 hrs to prevent deep infection :contentReference[oaicite:33]{index=33}
- Vaccinate against FIV/FeLV/rabies as appropriate to reduce systemic infection risk :contentReference[oaicite:34]{index=34}
