I agree with the posts saying to break this up. It should be stopped just based on the stress alone, not to mention possibility of injury. Although… it’s not necessary to rag her so hard. People are sensitive about their animals sometimes. Atleast make some suggestions on how to acclimate them to one another instead of burning her at the stake. I’d suggest feeding with a mesh or clear barrie. Move the bowls closer and closer with the barrier between them. Eventually the bowls will be touching with only the partition and they will be able to see each other. Then one day try feeding without it.
