I know from other persons they have been doing this to be more accurate or something... and I´ve known rats.. but not cats... how sad indeed... hopefully they were already gone... as i´ve heard soem of these rats go under anaesthesia.. get disected... then stitched... and woken up...

when I was at school.. they did worms and frogs... I say did as I skipped that part.. I just couldn´t.. not even the worm... and not even they were already dead... I just couldn´t...

but I´ve seen an autopsy of a puppy... I still cried.. but I didn´t do it, just watched for an answer.. (not my puppy, from a vet I worked for)
