I came across this nice little deal while searching for a little christmas present for my cats!
If you buy the play circuit, the massage centre, and scratch pad for £15 each, they will throw in another play circuit for free (remember to add it to your basket!), giving you the whole circuit for £45. delivered.
Other sites are selling these pieces for £14.99 also, but without the freebie you would be paying £60.
Lets see how the cats like it on christmas though!
