I might be totally wrong but we know the following:
1) Ray and his fiance were self-proclaimed "animal lovers", and working in the animal care part of Yale's research facility may mean that they wanted to ensure the animals' wellbeing
2) Annie dissected cats in high school which is pretty atypical as far as I know, and her research heavily relied on the use of animals (rodents, albeit, but animals nonetheless)
Is it not feasible that Annie asked Ray to provide her with a larger animal, like a cat, and since 95% of animals at Yale are rodents, this would be an unusual request. Having a cat himself, this could have infuriated him and they could have gotten into a scuffle with the fiance encouraging him.
I should put a disclaimer though that I'm a vegan and truly hope this is not true since it would bring a bad name to all of us mentally stable animal lovers out there...
