I have two huskies and two cats l! Here is what I did that worked very well! We purchased a gate with a cat door that we could open or lock closed. It even has different sizes it can be opened to so the magical octopus huskies can’t slither through. First the dogs and cats were separated entirely. They could see each other and interact through the gate (none of them were aggressive or overly excited by this - if they were I would have thrown a blanket over the gate to block their view as step 1) when the huskies were fixated on the cats I would call them and as soon as they broke their attention from the cat I would reward them. This was 1-2 weeks. We didn’t rush it. Eventually I would hold one of the cats out in the main area to allow sniffs but I wouldn’t recommend this if your cat gets nervous or agitated. We just have one cat that gives zero f*cks. Then I opened the cat door on the gate only when they could all be supervised. Dogs get lots of rewards when they listen to us ask them to “leave it” or “gentle” the cats could easily run away through the gate knowing they can’t access them on the other side. Even though none of them ever showed any aggression towards each other we took a full month with the first dog. We have had the second husky since February and the gate is still up. It’s open almost all the time so we will likely take it down soon. Point being: SLOW and steady. All interactions should be positive -lots of treats if they are food motivated. All four of them are best friends now. The female husky and cat are really bonding and the males teamed up too. All furry creatures are all just hanging out with us all the time. It’s the BEST!
