I was quite mortified a few months ago as Totti had to have spurs on his teeth done. I had been feeling smug as I felt his diet was perfect i.e. lots of hay etc. etc. so could it be genetic? he's 3 1/2 years old and was from a pet shop in a DIY store.... sold off cheap as they thought he was blind but lucky me... he is the love of my life but sorry, I digress.
So minor teeth problems yes... but at the age of over 3 when they appeared.
Good luck with your research Val.
