I have did the scent swap with a t- shirt, she hasn't hissed at that. However when they swapped rooms she sniffed his bed hissed and swatted at it LOL
Yes the brush is the residents usual brush and she loves being brushed with it.
I have been brushing resident cat with the same brush as the new kitten so they can get used to their smells. I brushed the new kitty a lot and when I went to use the same brush on the resident cat, she hissed at the brush and wasn't very happy Should I put treats on top of the brush so she can...
