I think you have ONE workable alternative - THE UNANNOUNCED VISIT FOLLOWED BY THE 911 CALL.
It requires that you call the police department in your father's town and 1) tell THEM you are going to check on your dad in the next day or two. 2) Tell THEM that you are afraid to be going, but you are worried for your father. 3) Then tell them there is the POSSIBILITY that you may need to call 911 for support. (Believe me, they will understand EXACTLY what you are saying - and doing.)
Plan to go on a weekday, at a time when there will not be too many people about. This will enable him to be forthright with you (a nice way of putting it...) and eliminate witnesses other than yourself.
Take him a nice casserole, dessert or other food you recall him liking in the past. (Put it in a dish or container you don't care about losing.)
If you have children, it is ok to take them with you, but LEAVE THEM IN THE CAR WHEN YOU GO TO THE DOOR. Park within sight of his front door, but make sure the windows are all up and the children are not able to hear your conversation. Also, you will need someone on call to pick up the children. If you do not have children, ask a sibling WHOM YOU TRUST to go with you, (but NOT one he particularly likes...)
MAKE SURE you bring a cell phone. If you don't have one, borrow one or buy a disposable one.
WHEN YOU ARRIVE, GO TO THE FRONT DOOR (facing the street,) ask how he is doing and ask how his girlfriend is. Then present the casserole and ask to be invited into the house. This may set him off. If it does, express your concern. Ask about the cat. From everything you've said, you will not be welcomed. HOWEVER, it is ok to AGGRAVATE HIM! (from what you have said it should be easy) Allow him to escalate verbally.
You should be able to predict his response - explosive.
THEN... CALL 911. Being on a cell phone you'll need to 1) give the address and your name. 2) Tell them you need HELP RIGHT AWAY - IT IS AN EMERGENCY. 3) Tell them you are worried that your elderly father may be a danger to himself or others, including yourself and his girlfriend... 4) Tell them you have children with you (if you do...) 5) Tell them that no one has set foot in the house for X years and that you are there to check on him and he has threatened you. 6) Tell them that through the door you smelled what might be a dead animal. 7) Tell them to HURRY.
This will lead to the arrival of a police squad car with two officers who will attempt to enter the house. They will insist. If they are not allowed in they will force the door. EMT WILL BE CALLED to take him to the hospital for a geriatric psych examination. If he does let the officers in and the house is as you describe, they will do the same. If the house is immaculate and you swear that he threatened you they will still take him in. Either way, he will get the medical work-up and psych examination he so desperately needs.
Last word of advice - don't tell anyone of your plan other than the person you choose to accompany you. If you cannot trust your sibling(s), tell no one and do this alone.
I was given these directions to protect myself from my mother when she was psychotic from unmedicated Alzheimer's. Fortunately, I never had to use it. BUT, these directions were given me by my mother's neurologist, her social worker, her attorney, AND the local police department... This was in New York State. ALSO, last but not least, EVERYONE who recommended this course of action said that the police were accustomed to arriving and finding the elder surprisingly cool, calm, and collected. But the police are NOT fooled. They rely on the 911 caller as witness.
Good luck!
