We adopted two cats from the RSPCA about five months ago. Both are very nervous and one still hasn't let us touch her. They seem to get on very well but in the past few days seem to have started scrapping more. At times it seems very playful but once or twice it has seemed a little more violent. After their scraps they seem quite happy to sleep on the same chair or hide under a table together.
I'm not used to having two cats so not sure if this is normal behaviour and they are just being boisterous or if I should be worried.
