You'd think after 5 years into this, this may have happened before now or at least this realization would've occurred to me before now: Always (ALWAYS!!!!) have a contact number (either the cell phone or the destination phone number) for your clients. That way, when you walk up to their house and their front door is ajar, you can contact them to hopefully get an idea of what is going on and you won't have to call the police. Or if you still have to call the police, at least you'll have an idea of what to tell the police. Lesson Learned the HARD WAY this morning. All was well... I am guessing the door just didn't latch when it was closed. **btw - this client has a rabbit that was safe and secure in her cage when I went inside. No pets escaped thank God.**
