Rajah is 5 months old today! AND, he lost a tooth. He was pawing around his mouth this afternoon after chewing my beautiful plant. I was not happy with him at all because nothing stops him once he wants to do something and so was a bit worried in case he was having a reaction to the plant, but he'd had a go at it plenty of times before without incident, so was a bit confused as to what all the pawing was about. My daughter came in about 5'ish and she held him down while I took a quick peek in his mouth. She spotted the bottom front fang hanging by a thread. It took one little yank and it came free. Rajah was a little disgruntled at the treatment, but was happy that the irritation was gone.
PS I only have 2 houseplants, one is a nearly dead love palm courtesy of Rajah, and the other is quite a large and prolific something or other, and seems to be able to take a lot of chewing, but I haven't a clue what it is. None of wikipaedia's plants that are deadly to cats match it. It has longish variagated leaves - pale green background with dark green stripes, and purple at the back. I can't identify it anywhere on the internet.
