After several calls to the Pest Control Company, they finally called back to admit that their employee "made a mistake by catching the two cats at the bin center" and that they were actually supposed to catch cats in Woodlands that morning. Luckily there was a resident who had seen the trapping going on and later informed Penny. So the 2 cats are now at AVA (one ginger boy and a tortoiseshell female). The pest control company (and caregivers) will try to claim them back on Monday morning. No wonder I was told there are no cats from our area at AVA, because they were recorded as being caught at Woodlands.
Two more tipped-ear cats had gone missing from the bin center earlier... but no one saw what happened. They probably were the victims of another "mistake" and it will be too late to save them now because AVA will keep the tipped-ears for only about 3 days before they are killed.
I guess many such 'mistakes' happen on a regular basis and it seems we caregivers have to make a trip down to AVA whenever any cat goes missing.
