I recently moved my 2 y/o outside for the summer. He has a heated house. I just got home and it's been raining on and off for hours, temp 70. He did not go into his house, he was taking shelter under some plants. Is this normal? I worry he will get sick after being in those conditions. Also I have a large area set up in my basement for him I plan to try a pig blanket, MVB/CHE, and an oil heater to maintain temps? Any input would be great. Thanks.
