"I can take my nod pork with my site?
Im going camping in Garner State Park. It is near Uvalde Tx. There are many shade, but survive the heat?
If it will be very warm where you are camping, I would like to find another home for your Guinea pig. They do not like too much heat. If the weather was cold, I'd say go for it. Make sure you have plenty of food, water and a cage. And check with other people pets such as dogs and cats. They may try to get your pet.
