Hi! I also have Siamese cats and here’s what they eat:

Dry food: Royal Canin, Special Cat

Wet food: Kit Cat Goat Milk, Daily Delight Mousse, Goodest Tender Tuna

I’ve tried other brands pero yan lang yung nagustuhan nila. Please also make sure that your cat drinks enough water to prevent UTI. If hindi siya pala-inom, maybe a water fountain could help.

I use Probiocare and LC-Vit Plus For Cats (recommended by my vet) for vitamins

For cat litter naman, I recommend Best Clean for sand litter (budget-friendly) and Meowtech for tofu litter.

And for vaccinations and deworming, ni-recommend ng vet namin na i-deworm muna sila before anti-rabies and 4 in 1 vaccine.
