Ask if an apprentice climber or employee is available if everyone else is unable to make the rescue. The information will become invaluable during the whole cat rescue experience and will save you time in the future if you need another cat rescue. Remember to make a list of whom you called, whom you talked to, and what they said. You'll need to know who you talked to if a climber shows up and another climber also agreed to come out. Make an immediate call to the other climber who promised to come out when the first climber arrives.
Nothing is more embarrassing than two climbers showing up at the same time for a cat rescue.
The list will prove valuable in the future if you ever need another cat rescue or tree work. You can save much time because you've already performed your research. Keep your list and notes on file where you can find them in the future.
