Great,I have a mustelidea in my lap.Cats seem to have one of two reactions to ferrets.They either hiss,growl and run the other way,or they are curious. From experience the curious cats are the easiest to integrate.I wouldn't worry about your ferret,I'd worry about the cat more.Outside cat or not they do recognize a fellow predator,and show respect,usually.Just watch them together for a while,make sure you supervise all playtimes. Jasmine will be in surgery as you read this,so send good thoughts.I'm the typical nervous mom,I just keep reminding myself it's for her own good.The last ferret I took in for a simple surgery,not invasive,had all 4 feet planted on the bridge before they brought him back.The old fart is stll stealing raisins,and begging cheerios.Jasmine has one of those plastic balls and she loves it.Her's was stolen from my grandson,and only has one opening.If Taz turns her upside down,she has nothing to push on to get out,though I'm sure she'd find a way.I just never wait for her to find it.She loves spinning in it,but not the dizzy afterwards.
