Unless your cat is strictly indoors in Thailand, they will be in danger. Street dogs are everywhere, as well as snakes and other predators. In the past 3 years, we've had 6 cobras in our garden.
If he is strictly indoors, you will need to find a house with aircon in the living area, because you won't be able to open windows/doors.
We have 9 cats here and have been through the learning curve.
Best of luck!
