With striking blue eyes, pale coloring, and sleek physiques, Siamese cats are sophisticated lookers with perky personalities.

Royal Canin Siamese dry cat food is tailor-made nutrition created just for the Siamese breed. This exclusive formula contains specifically designed levels of protein and fat to help preserve a long slender and muscular body. Highly digestible proteins and prebiotics promote healthy digestion. Essential nutrients like amino acids, vitamins, and omega-6 and omega-3 fatty acids give their coats a majestic shine. And the unique ring-shaped cat kibble is specially designed for a Siamese’s long and narrow jaw—encouraging them to chew thoroughly, and crunch away tartar buildup. Mix in or complement with Royal Canin Adult Instinctive wet cat food for a meal that’s sure to please.

Zero Stars if it was an option. Oh, I see Royal Canin still has their TAILORED NUTRITION campaign! Where is the Siamese Breed food? Since, Royal Canin has stopped making the Siamese formula, my flamepoint has gone from a healthly, muscular 10lbs to 13lbs! I've tried every formula, oh and the appetite control formula, really? Come on already, get back to work like the rest of the world!

Can't believe you are doing this to Siamese cats!

You have become a garbage company!! Shame on you for doing this!

Losing longtime customers

I urge Royal Canin to get more siamese cat food made and shipped to stores! I have not been able to find a bag since the Summer of 2021 for my two siamese cats who have eaten it for years! Unsure if they have stopped producing it or if this is the longest relay ever? Regardless, this was an overall lousy company decision, and they are losing long-time customers. While I have checked many pet stores, the WHOLE Royal Canin section is bare every time I check. Currently, the only place I can find it is in another country online.

I will NOT return to Royal Canin Siamese

I'm feeling abandoned by Royal Canin's decision to stop making the Siamese Cat dry food. I'm now searching for another brand and since they keep pushing back the return of this product I will not be returning to Royal Canin IF or when they decide to start making it again. ☹

Excellent food but can’t find anywhere

As of November 2021 I cannot find this food anywhere in the US and have resorted to buying a few remaining bags from Spain. I urge Royal Canin to produce more as it is the best quality cat food I have ever bought. I notice a major difference in my Siamese when she’s eating this vs. any other food. Please start producing again!

Bad Company Decision

I have been feeding the Siamese Adult dry cat food to my two Siamese cats for five years now and I can not find it anywhere in the market since Royal Canin stopped producing (on hold) this past spring do to them wanting to produce more of the Vet Diet food. I was told from previous customer service reps. that they would start producing it again in September 2021. I talked to a rep. today October 2021 and now they say they are not producing it till late 2022. So I am now suppose to change my adult cats to a different brand of cat food, if any cat owner knows that is very hard to do. At the recent cost of $38.00 per six lb. bag maybe it is time to drop Royal Canin and find a cheaper good quality cat food that I can feel will be around for many years!

Our kitty’s favorite

Our kitty has been eating this cat food since she was a kitten (well, she still acts and looks like a kitten at 14 yrs.). She love it just as much now as she did way back when. Thank you!
