CDC warns of aggressive cannibal rats

Officials say rats have resorted to open warfare and eating their young as closures reduce edible waste. “Many of these rats in our cities depend on their nightly food, which is the restaurants and hotels and bars and doughnut shops and everything that we consume on the go,” rodentologist Bobby Corrigan told The Washington Post.
Love is the virus. Love is infectious. Love is the CURE. Oh wait, maybe it's rats.

Rats, better known for inhabiting sewers and dumpsters, also love to settle in the innards of vehicles in cooler months. The warmth and shelter attract them, but it’s the wires and hoses that entertain them: Rats’ teeth grow constantly, and they gnaw on things to keep their teeth trim. Inside an engine bay, they can blow fuses, start fires and even total cars.posted by ZeusHumms at 11:46 AM on May 26, 2020 [13 favorites]
No one tracks rat damage to cars, but there are signs it is a growing problem amid a nationwide rat population boom that experts say may be fueled by a warming climate. In the fall, rats set a sedan ablaze in Manhattan. They’ve mutilated the cars of college students in Florida. In recent years, a half-dozen class-action lawsuits have been filed against auto manufacturers on claims that today’s eco-friendlier wiring is irresistible to rodents. AAA warns that modern cars offer a “smorgasbord of treats” for rats.
I wonder if there will just be fewer rats now.
Rat populations are pretty much always at 100% capacity. Kill 80% of the rats, they will quickly breed up 10 100% carrying capacity. So the rats will rebound as soon as restaurants, bars, and hotels start putting out garbage again. Interestingly, Milwaukee was one of the few NA cities that had some control on its rat population by draconian fines for violating garbage containment in the downtown area.No idea if that is still the case or not.

My three pet rats are all boys, from two mothers that someone bought and which turned out to be pregnant. Each of those female rats produced more than a dozen babies ('kittens'). My rats were sexually mature at 6 weeks of age, when they were not much bigger than mice.
Given the right conditions, they'd overrun the earth in a couple of years (conditions that include seafaring skills).

Living in a seaside town I was wondering what the impact will be on the local seagull population. In the summer they nest all over the rooftops, scavenging lots of food from tourists and people out at night, then things get thin in the winter and they get more aggressive, going as far as snatching food out of hands. So I guess that might happen early or it may be there is some impact on infant survival I guess?

I am in the suburbs not too far outside a semi-dense downtown area, and within about two weeks of the first closings I had a rat appear at my backyard birdfeeder. Took the feeders down for a week and that seemed to solve it, but over the weekend another one appeared. And it is fearless - it won't leave unless you get right up on it; the first time I was actually afraid it was going to lunge at me.

Rats and mice are among relatively few mammals to adopt the "make dozens or hundreds of kids, most of which will die before adulthood" strategy, rather than the "only have a few kids but actually put significant effort into keeping each of them alive" strategy. Just a small step from "eh, maybe a cat will eat them but who cares" to "eh, maybe I'll eat them, who cares."

Maybe the rats can assist with the Millions Of Cicadas Expected To Emerge This Year -- oh, no. Did Cicada Explosion Lead to Boom in Rat Population? (July 29, 2004) Officials in Alexandria and Arlington said the unusual insects -- which popped up in the Washington area in May and June after 17 years underground -- provided a feast for the area's rodent population, which they say is considerably larger this year and the source of more residential complaints.

My cousin is going through this. She's a traveling nurse and bought a fifth-wheel (a name I still don't understand) in order to go nomad from location to location. Four or five months ago she discovered a rat was living in it...somewhere...over the Montana winter. It has indeed eaten all the wiring, she hasn't been able to get rid of it and, consequently, has not been able to hit the road.

That might have been hunger, or alternatively what rat owners euphemistically term “the clean-up” - a wild rat’s instinct to eat any dead bodies near the nest for fear of the remains attracting predators. Even well-kept, non-stressed, well-fed domestic rats will often bury - and sometimes consume - the body of a cagemate who died naturally, acting on the same instinct.
(We’ve only ever had one of ours pass away in the cage rather than being put to sleep at the vet’s, but the rest just left him alone, much to our relief.)

Years ago I read Alan Weisman’s book The World Without Us (if you haven’t read it, it’s an examination of what would happen to the planet if you suddenly subtracted all the humans). I was struck by his point that the two species we are accustomed to thinking of as ultimate survivors, cockroaches and rats, depend very heavily on us. Cockroaches outside of the tropics would die out in a single winter absent artificial heating; rats, as we have seen, like our leftovers and in the presence of birds of prey (which currently are not often seen in cities), rats suddenly get to play an exciting new role in the food chain.

There was a petting zoo called Storybook Gardens in London Ontario that we were taken to as kids in the 60s. They had a big, wonky clock in the area central to the front entrance. It was the clock from hickory-dickory-dock and it had little windows with stairways for the mice to run up and down. There'd been a population explosion and the stairways were filled with babies. There was eating going on; like an ant farm of mice.

Rabbits are exceptionally soft and cute, but they are not immune to less-tactful cannibalism as well. I had remembered reading about this long ago, and quickly googling I see that there are plenty of very graphic accounts of people being horrified at what they see happening in their rabbit households. (And, interestingly, articles about the importance of meat-eating, both cannibalistic and not, in wild rabbit populations, especially during the winter.)

My central London neighbourhood has - like a lot of others - set up Covid-19 Mutual Support Whatsapp Group, which has been a mixed blessing at best since I joined it. Mostly it's used for arranging delivery of prescriptions or a loaf of bread for people who are isolating.
However I knew it was the right moment to leave the group when one of my neighbours posted a concerned question wanting to know - in all seriousness - had anybody thought about the urban foxes? Who was looking after them? Were they OK? Were they hungry, now that the restaurants are all closed? Should we set up a feeding rota?
I can only imagine how he's gonna feel when he learns about the plight of the rats...

Just so no one gets the idea that rodent infanticide and/or cannibalism is exclusively a rat (or hamster) thing... a lot of rodents do it. In fact squirrels, which I know some people here label as "cute", sometimes will resort to infanticide during times of plentiful food.
