When changing my cat from Hill's Prescription ID (dry diet) to Van Patten's Natural Balance, should it be gradual, or can I just take the old food away completely? I wondered if there could be a stomach problem?
Everything I've seen on this subject says to do it gradually. Make about 1/4 of the serving the new food to start. Every 4-5 days add a lttle more new and a little less old, watching for digestive upsets (constipation, diarrhea, vomiting) as you go. Within 2-3 weeks the changeover will be complete.
Mary T is right; plus you could double-check with your vet.
Add some new gradually to the old. If you dont do it this way the dog will more than likely get diarreha. Check with the vet first. ~Janette~
