We have two Ocicats, indoor cats, litter-mates who turn 10 next month. For all their lives so far they have done very well on Wellness wet food, supplemented with raw meat twice a week. No dry food. When I asked the vet to recommend wet food for ageing cats he said it's best to stick with the existing brand, if possible, as it contains taste elements that already appeal to our cats. The only problem is that Wellness does not make a specialty older cat food but say that their food is suitable for healthy cats of all ages. Should I attempt to transition them to a "senior" food? I am happy with Wellness and so are they. Ocis are notoriously greedy and we need to pay attention to what they eat. They are never given human food or snacks and are in very good shape. Thank you!
