weird thing is that it doesn't matter who pets the same squiggins, the ratings keep going up. If I had a ratings of 1000 and gave him over to hopkapi who clicked pet, he would get the rating of 1001, and 99 clicks later I would get back the squiggins and upon petting him once would get a rating of 1101 and so on. Quite silly : )
Besides if I'm not mistaken, the ratings started at 12.. Maybe somebody already petted this cat before I found him.
