HWS Mortality Database

The passing of a hedgehog is one of the most difficult times for a hedgehog guardian. We hope that by collecting information about the causes of hedgehog deaths, someday we can learn more about how to keep them healthy.

If you have a departed hedgehog, we are asking for your help in our quest for knowledge. Please fill out the survey to the best of your ability. There will be questions you may not be able to answer, and that is okay. Every little bit of information is one piece of the big puzzle and is useful.

We are also interested in the behavior as well as the mortality of hedgehogs from the 2009 Texas rescues. Each person who adopted a rescue from the US Global Exotics seizure agreed to notify the Hedgehog Welfare Society at the time of the hedgie's passing.

We thank you in advance for your selfless efforts to share information with us. Again, we are sorry for the crossing of your hedgehog.
