Wet food or dry food? my opinion after years with cats

I had cats in Osaka for about 15 years, and when I moved to Bang Lamung I was surprised how fast the food goes bad in the kitchen. Wet food can go bad in 1 hour if you leave it in this heat. So my answer is: dry food for every day, and a small amount of wet food as a treat or for water. Many Thai people here give only dry food to their cats, and at the vet clinic they also said cats need more water. Wet food helps with that. Some cats do not drink enough water and then have problems with their urine. My friend's cat had this problem, so the vet recommended wet food at night. I am not a vet, I just watch my neighbours' cats and I see the difference. The cats with wet food are often less thirsty and more active. But that is just what I see, please check with a vet for your own cat.
