I imagine that dealing with all those animals required considerable time by Brits on the ground in Kabul.
Kabul is not a safe place... and putting Brits at significant risk to save some dogs seems rather strange.
There are not endangered species... and there are plenty of abandoned cats and dogs which end up being put down in the UK each year. Those who wish to rescue animals can visit Battersea or the RSPCA who will likely be very happy to talk... and nobody is put at risk from bombs exploding
