## Why this drug is commonly compounded

Commercial human gabapentin oral solution contains xylitol, which is highly toxic to cats and dogs. The standard 100 mg and 300 mg capsules don’t fit weight-based dosing for cats or small dogs. Compounded xylitol-free flavored liquid solves both problems.

## Why Chewy Pharmacy can't fulfil this prescription

Chewy stocks the commercial human gabapentin oral solution, which contains xylitol. For cats, that’s a safety contraindication. Chewy does not offer xylitol-free compounding.

## Species-specific benefit

### Cats

Cats need precise mg dosing for anxiety (50–100 mg per dose). Commercial liquid contains xylitol — NEVER safe for cats. Compounded xylitol-free liquid is the only safe daily form.

### Dogs

Small dogs and toy breeds need 5–10 mg/kg dosing that doesn’t match 100 mg/300 mg capsule strengths. Flavored compounded liquid solves precision and palatability.

### Rabbits

Rabbits with chronic spinal pain need 5–15 mg/kg dosing twice daily. Compounded liquid allows accurate dosing in 1–2 kg pet rabbits.
