A recent fad states that plastic water bottles leech toxic chemicals. Is it true?

Today we're going to place our plastic water bottle, which has already been used three or four times, in the car on a hot sunny day, and then drink its noxious chemical contents to see if we get sick and die. The idea is that chemicals in the plastic get released into the bottle's contents when the bottle is reused, and especially if it's heated up.

So let's point our skeptical eye at the issue and see whether it has any merit. Do we need to be concerned about this? The only really fair answer is that it's a complicated question. "Plastic" is not a single compound. There are almost as many different types of plastic as there are types of substances contained by them. Some plastics do contain poisonous chemicals. Some plastics do leech chemicals into liquids. In some plastics, this process can be accelerated by heat. The reason for this variety is to provide the product distributor with enough choices that they can select a plastic type that's best for their product. This permits a distributor of drinking water to use a bottle that is absolutely safe to contain water for humans under the whole temperature range that the bottle is likely to be subjected to. But, put gasoline into that same bottle, and you might see that plastic dissolve away. Plastics are designed for their particular application, and misusing a plastic product can produce undesired consequences.

One time, in college, I was moving to a new apartment a block or two away. My brother and I had built a koi pond, and we needed to move the fish and store them long enough to build a new pond at the new place. We went out and bought a cheap plastic kids' wading pool. We put it in the garage and filled it with the hose, treated the water with all the usual fish-friendly chemicals, and walked the koi over in buckets and placed them in their new temporary home. Well, we learned a harsh lesson about chemicals in plastics. After a day or two the koi didn't look so good. Some of them died. Then all of them died. It was pretty horrible, because, and I'll spare you the details, they didn't look very good. We had no idea what the problem was. Was it the shock of being transported? Did we not add enough stuff to kill the chlorine? On a whim I called the manufacturer of the swimming pool and asked if they knew any reason why this would happen. They did. On products like this, they always add a mold inhibitor to the plastic. In this case, they used cyanide. For a children's pool, they add a safe low level of cyanide that's harmless to the children, but is enough to prevent mold from growing that would make the pool gross and unsightly. Evidently, a level of cyanide that's safe for a human is lethal for a fish, since they breathe it directly into their blood through their gills. The guy we spoke to was the company's head scientist, and he seemed to relish this rare opportunity to discuss his work. He went into all sorts of detail about their different products, and how they use the right plastic for each different job. Ever since then, whenever I work on a koi pond, I always call the manufacturer of any plastic products I'm using and talk to their chemists.

To get away from them, as they have teeth.
Is there anyway you can block off part of the bathroom, so she can get away?
With mine they are able to leave the whelping box and the pups aren't big enough to get otu of it..so she can get away fom them, but still keep an eye on them and return anytime she likes.
The easiest thing would be to spend 10.00 on a plastic kids pool. easy to clean..easy to work with..and cheap.
