Warming temperatures are unleashing parasites in places they have never been before.

Parasites once locked to warm or tropical regions are now showing up in neighborhoods that never had to worry about them. Rising temperatures and shifting seasons are rewriting the rulebook for where parasites thrive. This is bad news for pets, who often encounter these invaders before we even know they have moved in. Scientists are warning that what we thought we understood about pet parasites is changing faster than expected.
