So my cat Oscar is the 4th of the bunch. He is not fully comfortable with the other cats so when they come around he growls. But all of the cats have walked right up to him and sniffed them and he hasn’t so much as looked at them. He also is very playful and his favorite toy is plastic and he’s not reacting to that either. He’s not reacting to being pet and he’s a really loving cat so I just want to know if there’s any reason for concern. Thanks
