I only have 1 cat. She seems to show no interest for the plushie
Though cat and me do sleep together in my bed. And you occasionally see her in my pictures!
(I had written this post before 29-11-2019 but I put it in my queue. Unfortunately my cat passed away on that day. There are numerous posts of me and this cat on my blog which I will keep there for the time being. In this case, I want to answer this ask purely out of politeness. Rest in Peace kittycat.)
