D/d Hills perscription Royal Canin equivalent?

Hey my cat needs D/d Hills perscription formula food. However I have recently relocated to China, and I can't find that brand. Before I bring my cat over as well, I need to find a food for him. Royal Canin is more common here, but I don't know if they have an equivalent formula for D/d. And I can't ask the vet, as I'm overseas.

Any help/ideas?

I'm not that familiar with prescription foods but what I found it sounds like a hypoallergenic type food.  It said it is for the skin but it's the novel proteins, what I found was venison or rabbit and potato or pea.  Royal Canin makes some hypoallergenic foods.  I know they make rabbit and potato, I don't know if they make one in venison.  It doesn't have letters on it, it's just hypoallergenic.

Based on the info I can find online for the Hills d/d, the ingredients do indeed look somewhat similar to those of the Royal Canin Selected Protein prescription line. That particular line comes in three varieties, (each in wet & dry)... Pea & Rabbit (PR), Pea & Venison (PV), and Pea & Duck (PD).  The Royal Canin Selected Protein does have less diversity in it's ingredient list, however. But my guess is it is probably closest to what you are feeding now. Royal Canin does not have a variety labeled specifically for sensitive skin, that I am aware of.

One of my teenage kittens is currently prescribed the Royal Canin Selected Protein Pea & Rabbit (PR). He will eat the kibble, just enough each day to barely get him by. He doesn't really care for the canned, but will eat a small amount at each meal if I really water it down into a thin gravy on a saucer. It has not been calorically dense enough to meet the needs of a 9 month old kitten that is still growing like a weed. The result after 7 weeks, is an underweight kitten.  We offer him as much as he wants to eat, and he hits a wall at 3/4 cup per day...he will not eat more than that. (The only reason he is still on it is because we are waiting for the results of allergy testing that was performed last week...we will be switching to something that better meets his needs once those are back).

So in addition to comparing the ingredients, you definitely need to compare the nutritional analysis (protein/fat/fiber etc) and calorie content. I only did a cursory glance so you'll want to compare in detail, but it looks like the Royal Canin PR that we are using, has both less calories per cup than the Hill's d/d (a good 100+ calories less per cup), and is also lower in fat. Those types of difference are something you definitely want to take into consideration along with the ingredients lists when choosing a new food for your cat.
