My cat had a problem in his eyes years ago, and had to go to an ophthalmologist vet every few months for a while.

I still think of that as a lost opportunity.

Tell me about it! I live in one of those countries! I work with volume and area conversions constantly in my work and equipment from both European and US manufacture. Nothing causes as many mistakes and miscommunications as imperial.
