Care, Cost and Maintenance
Administer Properly
Follow dosing instructions. For gels, place on paw or mouth corner; powders mix well with wet food. Observe your cat after first dose.
Monitor Hydration
Laxatives work best with adequate water. Ensure fresh water is always available to prevent impaction.
Know When to See a Vet
If constipation persists beyond 48 hours, or if cat shows distress, vomiting, or anorexia, seek veterinary care immediately.

Offer a small test dose on your cat's paw or a treat before full administration to gauge palatability; if rejected, try a different flavor or form.
