Sorry, haven't had a chance to log on for a while.
Milly's Mum - what is a TNR charity? Not come across that one before.
I always feed strays when I can, on holiday. Last year in Spain there were loads in one particular area near a batch of restaurants and my kids & I regularly bought cat food & fed them which made me feel I was doing a little bit to help. There was one lady I spotted in Tenerife many years ago, who walked along the pier & fed goodness knows how many cats, including swapping out dirty bowls with clean - it was amazing to watch her in action, I really admired her dedication to strays.
Helen - I wasn't able to take piccys of this year's strays I came across, if I drew too much attention to the cat & kitten the waiting staff would chase them, so I was happy to have them hiding under the table to be fed discretely!
