This could all be prevented if people were not too lazy to open & close their doors for their pets at need, instead of cutting a hole in it for them to run loose.
It only takes one mad squirrel; or a possum, coon, or skunk; or an enterprising tyke/teen burglary team to make believers out of them. Or, tragically, one squished cat or dog.
Pets, unless invited & taken elsewhere, belong in the home & yard of their owner, for both their safety, and the safety of the owner’s finances.
