Why these species should be converted into vegans and/or herbivores

Species:

1. Felis silvestris silvestris
2. Felis silvestris lybica
3. Felis silvestris domesticus
4. Felis lybica lybica
5. Felis lybica domesticus

Reason: I genuinely and honestly want these species to understand that it’s morally wrong to intentionally kill animals

Furthermore, biologists and ecologists should ensure that biologically similar species ALSO get converted into vegans
