Well, you are luckier than us, Ela.
I've had 2-3-4 kittens at once. I've seen 2 adult cats
halfway in a trap before, but one has always shoved the other out of the way before it sprung.
A short while ago we loaned a trap out and it was delivered to the vet with 3 females in it. We are 99% certain they were not trapped but just placed in it by the person, who wanted to get rid of them all in one go.
