I agree with Uabassoon. I'm sorry if you were surprised by
the ear notching, but they were feral vouchers you used. Did
you take the kitties to your own Vet or bring them to a clinic?
Sometimes they do multiple syay/neuter procedures each day
set aside for just ferals & they do notch the ears. Are you sure
about the cutting off of half the cat's ear? Baby cats don't have
very big ears to begin with & maybe it seems excessive to you
right now. Nurse the two with problems & get them well. Good
luck to you.
