Bruno sounds cute - I have an Abby too.
Sorry to hear that your other piggies have died. The environment you described (hot and windy) isn't good for guinea pigs, as you have discovered. I'm sure Bruno would love to live inside, and it would be much safer for him. I'm not sure if you can get the materials for a C&C cage in the Philipines, but you could probably make one - maybe wire mesh walls and a plastic sheet for the base.
Is Bruno neutured? If he's not, please don't put any more females in with him, as you will end up with a lot of babies! I suggested some places to look for a friend in your other thread. He would probably get along with a baby male, or if you got him neutured, a female.
I hope you can find him a friend! Feel free to ask questions - we are here to help
