Sorry to hear that - she looked a real nice cat - You did the right thing and we did same with Holly - She had problems and all she did was eat sleep and poo and she was having no life so we made the decision and it was tears all the way - took a year to get over it - Never had it so bad with our other cat's but Holly was a rescue and we felt we had let her down.
RIP Izzy
