Condition-Specific Protocols
1. Dental Abscesses
- Higher range dosing (15 mg/kg)
- Continue 5 days post-drainage
- Combine with clindamycin for anaerobes
2. Urinary Tract Infections
- Extended duration (7-10 days)
- Urine culture recommended first
- Adjust based on sensitivity
Formulation Considerations
Oral Suspension Preparation
- Reconstitute powder with distilled water
- Shake vigorously for 30 seconds
- Refrigerate (stable for 10 days)
- Discard if color changes or precipitates form
Administration Techniques
- For reluctant cats: Mix with tuna juice or chicken broth
- Pilling method: Use pet piller for tablets
- Suspension dosing: 1mL syringe placed in cheek pouch
Adverse Effect Monitoring
- GI signs: Vomiting (5% of cases), diarrhea (8%)
- Allergic reactions: Facial swelling (rare but serious)
- Appetite changes: Usually transient
Contraindications
- Known penicillin allergy
- Severe renal impairment (adjust dose)
- Concurrent methotrexate therapy
Conclusion
Proper Amoxil dosage for cats requires careful calculation based on body weight, infection severity, and individual patient factors. The typical range of 12.5-25 mg/kg every 12 hours provides effective coverage for most feline bacterial infections when combined with appropriate formulation techniques and administration methods.
