My cat brought a frog in the other day... I thought it was a leaf (upside down) 
anyway when I went to grab the frog (and rather foolishly as was on my way to work so in a rush) may not have been best pleased. cat then hissed at me... charming. was this because I'd taken said frog off him?
also he has very long claws - longer than other cats I've had but doesn't need them clipping and long front teeth (fangs) too. normal right? any concerns there? i think he has got to be a better fighter owing to these weapons...
