We collected our new kitten over the weekend, he's a 5 month old Maine coon called Maximus (Max for short). He's very sweet and friendly, our adult cats have been very curious, we've done lots of sent swapping so let two of them see Max. One hissed and ran away but he's been back to have a peak and the other hissed and then laid down on the floor and just watched Max.
Pretty good going so far so while there all happy we'll continue supervised visits between them and hopefully things will continue, lots of treats and praise for them all as well
