## Questions & Answers

**Q: Does this work better than the Classic? I feel like my cat is getting used to the Classic and it doesn’t calm him as much as it used to.**
A: I have used the multi- cat on & off for years with excellent results, but I wanted to give the optimum.  Not sure if it's necessarily better (both are equally effective for us) but it definitely works faster.  For your situation, switching to a different formula is worth a shot.

**Q: Can the same diffuser i have for the multi cat be used for this?**
A: The instructions actually say to not use another brands diffuser for the refills, and not to use another brands refills in the diffuser. It does not specifically say to not use another one of their own diffusers. I will say I used my old multi cat diffuser and it was fine and worked well.

**Q: Can this be plugged in 220v or just 110v?**
A: I believe it would only be safe to use in 110 volt.

**Q: Can you use this in a dog friendly home with two cats?**
A: You may want to contact Feliway directly for the best answer. That said, the cat pheromones shouldn't effect your dog. If your dog is a chewer I recommend plugging in somewhere the dog can't reach it since it's ball shaped (or train the dog that it's strictly off limits).
