Help...My Cat is Suddenly Aggressive with My Dog Out of Nowhere

Hello everyone…

I need some urgent advice. My female tabby cat has suddenly become aggressive with my female Bichon dog, and I don’t know what to do.

For context, they’ve been in each other’s lives since my cat was a kitten, so they’ve been together for years. My dog is a couple of years older than my cat.

This started a couple of days ago when my siblings and I were watching a movie. My dog jumped off the couch, waking up my cat, and my cat instantly attacked my dog, injuring both my brother and the dog.

Schedule a vet visit for both pets. Sudden aggression could be due to underlying health issues or pain. Rule out any medical causes.
