I don't think they need donations. But vets or people who work with animals suffer from such bouts of depression and trauma that vets disproportionately fall to suicide more than the general population (1 in 6 vets in the US have contemplated suicide, and are between 1.6 to 2.4 times more likely to commit suicide than the Gen pop). Which makes sense considering the nature of their job. So it's probably sth to show appreciation and support for the vets.
