Multiple Landings
Chippy, for no more than your curiosity!! Any more than 10 movements from any one site in 24 hours constitutes multiple landings i.e. 5 landings and 5 take offs. After this number of movements (public transport aircraft / operators) are required to provide full fire fighting facilities (RFFS). Private Cat don't have to bother.
As for animals, any low level stuff has to take these into consideration - plenty of problems with the CLAIM everything and anything nature going on!!
