I have a calico cat (4f) and my roommate's golden lab dog (5m) in a townhome together. The cat has her own space for litter, food, and a bed. She also has toys in the main space. Generally the two ignore each other, but are not friends by any means.
The past day the cat has been hissing, growling, and fluffing her fur. If given the chance she attacks the dog at the face. The dog has done nothing to taunt the cat or bother her. It is all her going after the dog.
When this has happened in the past I separate the cat to a small bathroom for a short while, not knowing what else to do. This has not helped today.
I am at my wit's end. Are there any suggestions? Please, anything is appreciated.
