Pet-Safe Antifreeze

Pet-Safe Antifreeze

Not only is regular automotive antifreeze poisonous to pets, causing kidney failure and death, but it tastes sweet and attractive to them. What a terrible combination!

But there is a new, less hazardous antifreeze option. Find out what kind of antifreeze to buy to help keep your pets safe.

The toxic element in traditional antifreeze is ethylene glycol. The new kind of antifreeze contains not ethylene glycol, but propylene glycol, which is somewhat safer. In fact, propylene glycol is found in pet foods, cosmetics, and over-the-counter preparations.

One brand of this newer type of antifreeze is SIERRA, made by Safe Brands. A 50/50 mixture of SIERRA and water will protect a car’s engine to -26F; greater protection can be obtained by increasing the ratio of antifreeze to water, according to the company.

SIERRA is available nationwide for about a dollar more per gallon than traditional antifreeze. Many of us feel the price is little to pay if it eliminates a serious threat to our pets.

To be on the safest side, however, keep ANY antifreeze well away from your companion animals!

It is not a safer alternative, it is slightly less toxic and will cause death if ingested. Also it is not compatible with some cars and cannot be used throughout the motor industry. However, there is a company in Wales who have created a totally non-toxic EG antifreeze which will not cost extra to produce. Some manufacturers already put a bitterant in their antifreeze preparations but not all. My charity is campaigning to have antifreeze preparations banned in the UK/EU unless they contain a bitterant. It has been done in several states in America by a 11 year old girl no less. Please consider joining my campaign on Facebook and Twitter. It's a global issue. Lets protect our pets and children from this horrible chemical that KILLS! Thanks x
