Felocell (TriCat) Vaccine by Zoetis

Felocell vaccines by Zoetis are routinely used to immunize cats and kittens.

• Felocell 3 (TriCat): Protects against feline viral rhinotracheitis (herpesvirus‑1), feline calicivirus (FCV), and panleukopenia virus (FPV), supporting immunity against prevalent and potentially severe viral conditions in felines

• Felocell 4 (TriCat + C): In addition, guards against Chlamydophila felis, further broadening protection during periods of high communal exposure .

These modified-live vaccines are freeze-dried in single-use doses and require reconstitution with the provided sterile diluent. Once administered (either subcutaneously or intramuscularly), they stimulate strong, long-lasting immunity; studies show antibody titers persisting for 12–36 months post-booster

Usage

• Target Species: Healthy cats and kittens

• Indications: Prevention of feline viral rhinotracheitis, calicivirus, panleukopenia; Chlamydophila felis inclusion with Felocell 4

• Vaccination Schedule:

  • Felocell 3: From 9 weeks, 2 doses 3–4 weeks apart

  • Felocell 4: From 12 weeks, 2 doses 3–4 weeks apart; for kittens under 12 weeks, revaccinate at 12 weeks

  • Annual boosters recommended, modified based on risk

• Administration:

  • Reconstitute freeze-dried vial with sterile diluent

  • Administer 1 mL subcutaneous or intramuscularly

  • Use low limb injection sites to reduce sarcoma risk

• Storage: Keep at 2–7 °C; do not freeze; use vial immediately after reconstitution

Features & Benefits

• Broad Protection: Includes core viral antigens, with Felocell 4 offering additional Chlamydophila felis coverage

• Rapid & Durable Immunity: Established titers persisting up to 3 years after booster

• Human & Feline Safety: Contains gentamicin preservative; low reported adverse reactions (< 1%) such as mild fever or lethargy

• Convenient Packaging: Freeze-dried unit doses requiring simple reconstitution

• Licensed by Zoetis: Veterinarian-supervised practice ensures correct administration and monitoring

Note

• Avoid vaccinating pregnant queens

• Mild post-vaccine reactions (fever, anorexia, ocular discharge) reported in ≈1% of cases

• In case of severe reaction such as anaphylaxis, administer epinephrine immediately

• Injection site selection (low on limb) advised to minimize sarcoma risk
