Im having cat /neighbour problems.. My cat keeps getting into her house ( though I think she has encouraged it in the past). She rang me at 6am this morning to complain that he had been in at 3am eating her cats food, keeping them all awake and 'terrorising' her 3 cats .
Hes 14 diabetic no teeth, and really good natured , but yes he does seems to be raiding peoples houses.. Trouble is I dont really think I can keep him in all the time , he has always been an outdoor cat..
He's out again now . I bet hes round there again..
He lost his 'dont feed me collar' a few days ago .. Today she said she had it and then left it on her front fence for me to collect. It still looked totally pristine and didn't look like it had snagged on anything. im wondering if she took it off him.
.Ive never met her, She doesnt answer the door and they are the 'difficult family' in the road .
Quite frankly its making me anxious.... but if hes being difficult and wont have any quality of life if i have to shut him up, I'm worried that the only answer is pts.. 
I'm probably overthinking all this as I too was awake at 3am..
