Well I wasn't far off with my guess for his age ... I said he would be 5 months in the middle of December and the adult canine are now just starting to push through. Kitten's adult canine come through at 149 - 153 days - so yeah now we know. I think he's still quite small for his age, but so was Perry. Perry is still quite a small cat especially when he's standing next to my stunning black panther!
