Possible heat stroke

Question
We live in a trailer and while we have a in the main room, my daughter's room can get a little bit in the afternoon. My daughter went in to play with our of and he wasn't able to walk. She brought him to me and I could see he was lethargic and breathing very quickly. I Googled to see if they could get heat stroke and what to do. He had a number of the symptoms and I took the back legs not moving to be an indication of the  weakness that they mentioned. We sprayed him with water. And fed dhim lettuce and even gave him some water in a syringe. He's eating well and is even moving his legs a bit. Have we averted a crisis or do I need to watch for anything? (BTW, We will be putting his cage in the living room with the ac)

Answer
Yes, you averted a crisis. Although guinea pigs can take cold they do not do well with heat. When overheated they can quickly die. If taken outside and left in the hot sun they die within 15 min. The kidneys shut down and they suffer heat related brain damage very quickly.

If that happens again fill a bowl or the bathroom sink with cool, not cold, water. Put him in the water up to his neck. Take him out dripping wet and sit him on a towel. Sadly, depending on how quickly their bodies shut down, sometimes all the measures you take do not work.

Should your air conditioning go out you can put some water in your sink and allow him to swim for a minute or two. Then return him to his cage while still wet. Keep his body wet to prevent the overheating.

I'm glad to hear he's eating and drinking. That's the best indicator of his well being. When they are sick they refuse water and food. When you're having a hot day try to give him lots of wet lettuce to help him stay hydrated.

I'm glad everything went well for you. It would have been a real crisis for your daughter had he not survived.
