Not sure if the tramp was replaced befor... It is actually only one side that is starting to to wear through. I am not sure but it looks a bit like someone used some type of cleaner that might have caused damage to the vinyl. could be also that the cat was sitting outside for an extended period of time and while the rest was covered some portion of the left side of the tramp was exposed to the weather. I will post a pic if I remember to take one. It does not look like the typical death of a tramp.

Thanks,

Patrick
