My poor cat, Frank has always been an outdoor cat and loves the outdoors, He has recenlty been diagnosed with FIV and we have been advised to keep him in, but he is so unhappy, my mum insists the my other cat, Max is still going out and it seems really unfair to have Frank stuck inside watching Max go out and play. He is so desperate to be outside again but its just not safe for him or other cats in the neighbour hood. Do you you have any suggestions to make him happier inside or let him out with him getting into trouble, he wouldn't like a lead at all, he fought his way out of a collar in three days.
