yes rabies first thought. Distemper is another possiblilty, common in raccoons and will cause similar symptoms. In both cases people and pets, livestock need to be kept away from the raccoons. We are allowed to dispatch them hre and have them tested for rabies.
We had a raccoon about 6 years ago near our house like this. Would sort of wander around in a corner of the yard about 3’ x 3’. Fall over, get up and hobble around, etc. Wasn’t feisty at all - but yes - like a zombie. Suburbia, so I called animal control but they were busy, called the private animal guys, they were busy. The one guy could come but was $100 or something. He was nice. “Yeah - it’s distemper - it is wiping out the coon population. Just kill it.”
But - I was reading that that is illegal so I called our police non-emergency number. Quite town and a cop was soon there. Scratched his head “Well, I’d just shoot it - but can’t with all of these neighbors.” I told him I’d just kill it but that is against the law.
“Huh? Killing a dying raccoon is against the law? That’s stupid. Well - I won’t tell anyone if you don’t tell.”
After he left I bonked it over the head with a sledge hammer a few times. This after spending hours on the net, making calls, etc. and trying to do the “right” thing. Well - it beats my neighbor. A squirrel fell out of his tree and got hurt. He spent hundreds of dollars at the emergency animal clinic and it still died!
By the way - my kids love the Walking Dead show about zombies. Rabies is sort of that - where the virus takes over your body - even making you not want water (which adversely affects the virus somehow). And there is some bee that can sting a spider, and the spider will spin a hive or something based on the bee’s design! Several other types of that strange stuff. So - I tell them that one never knows - maybe zombies could be real some day. (Insert “smart-phone” joke here.)
