We are owned by 3 cats , and it was a slight concern for me when Moose came home. The cats, Sobe, Cosmo and Baby Rue are used to living with Fwirly, who is a highly energetic dog and they do fine with him, but I didn't know if they'd be fine with Moose too. They are indoor cats only and this is a small house, so it had to work out.
Well....we brought Moose home, he was 3 months old when we got him. Cosmo and Baby Rue hid right away, which was ok. Sobe on the other hand was going to try and let this thing know who is boss in our house and was trying to get Moose's attention.
Moose had just been on the road for 5 hours, coming home with his new daddy and human brother and was tired, thank you very much, so while Sobe pranced and jumped in front of him and tried with all his might to get Moose's attention, Moose yawned and fell asleep.
You should have seen Sobe ! One does not ignore a cat !! But Moose would not chase or even come closer, no matter what Sobe tried to do. Finally, being so frustrated and fed up, Sobe walked right over to Moose, meowed at him and shoved his behind against Moose's nose. Moose was happy to oblige and took a nice long sniff . Ever since that moment they have been best friends. In total it took about an hour with Sobe.
Baby Rue thought Moose was one smelly area rug that we got, her curiosity got the best of her after a day, and she went to check it out. Moose showed a little interest but was not willing to chase her. When she finally got him interested enough to look at her, she hissed and lifted her paw which was enough for Moose. He backed off. Baby Rue knew who was in control and used her act a few more times, but has yet to be chased by Moose ( he's been part of the family for 3 months now).
Cosmo was very skittish at first and was petrified of Moose. It took Cosmo about 4 days to come around and now they are best friends and Cosmo is even teaching Moose to hunt moths ( when I can catch them and bring them in the house, lol ).
What I noticed about Moose compared to Fwirly is that while he's interested , he doesn't really chase the cats. He will if they are playing but seems to be respectful of them if that makes sense. Mind you, I have seen the cats chase Moose more than the other way around because he does like to steal their toys and both Baby Rue as well as Cosmo will chase him to get their toy back.
