Please let us know what happens (if/when they catch the person/s).
Anyone that can hurt an innocent creature deserves to be in jail not walking around free.
My sympathies go out to the owners.
Dogs & cats can get along very well. I have two dogs (60 lbs each)and two cats (plus birds & frogs). When I introduced my dogs to my first cat Snowball (aka Spastic Kitty) I kept them segregated at first. When the dogs were outside, the cat was allowed to roam the house. When the dogs came...
I'm very sorry for your loss.
Is there any way you could build Georgie an outdoor pen (if you attatch it to a window he can go safely in & out as he wishes)? This way he gets some room to explore plus fresh air, but he is safe from other possible hazards.
Everyone has given such good advise I can't really add anything except patience patience patience! A good interactive play time can help tire them out and I've noticed that if I give mine a little treat just before bed time they go off & have a snooze.
Thank you for not bringing your kitty back...
