I would not remove the canine teeth unless they are diseased.
I would look at potential causes of stress in the cat’s living arrangements and attempt to treat them before removing healthy teeth for an owner’s convenience.
If the cat it biting because of a behavioral issue, and you then remove the teeth, you have done literally nothing to address the cause of the issue. If the cat was stressed, anxious or in pain it will still be stressed, anxious or in pain.
I would approach the situation by performing a physical exam, and if that’s normal proceeding with environmental enrichment, pheromone therapy tryptophan supplements or even anxiolytic medication.
I’m going to assume that your coworker had the cat declawed because he was scratching her, and as the underlying cause was not addressed he now bites instead.
If she does not want to investigate and treat the underlying cause, which can be confronting because you may realise you haven’t done the best you could by your pet, rehoming is an option. The cat is likely to have needs that she isn’t meeting.
I would not remove the canine teeth from this cat. It doesn’t solve any medical or husbandry issues, it doesn’t consider the cat’s mental wellbeing and it’s against the interests of the cat. I would be livid if I found out a colleague of mine went ahead and did this.
