A smildon

 

Probably big cats or a bear

 

Technically the smaller the deadliest, fleas/mites carrying an active form of the virus and you're done. Further down then mice/rites, can bite you in your sleep anytime.

Bigger animals I'm not so sure they'd be a threat, after all human zombies cannot run despite humans being able to. Thus I'd expect a zombie bear/cougar etc to lose the co-ordination as well, thus they';d be plodding/staggering after me and being rather vocal about it.

 

A unicorn. Because reasons.

 

If mosquitoes or any other types of insects would get infected and could infect us, we're screwed. There would be zero hope in surviving and rebuilding. Mice would be an awful one too. They're small, could easily get into settlements, and there would be so many of them out there without proper pest control and tons of food to feed. I can't see bigger animals being much of a threat.

 

Could you imagine a Rhino zombie? One giant horn comin at you with thousands of pounds of beast headin your way!!!

 

Lmao I asked my niece this question and her response was "a shark". Lmao I love her even if she is blonde..

Zombie elephant would be scary as shit. As would bears, and all other big animals. I don't count mosquitos as animals though personally . Lol

 

Cheetahs would be terrifying, provided they escaped zoos or if you were to be in Africa...

Horses would be scary. They have attitude.

Mice could be scary in that they're super common and you may never see 'em coming!

 

Any animal that could outrun a human would be really scary! Like some dogs, greyhounds would chase you down with ease!

 

I'd take a bear. Got to stay away from the mice & smaller, that'd just be game over for humanity. Speed animals like the big cats won't be a problem -- zombies don't run. Bears though have bulk and power, and don't tend to stop for anything when they're angry. They'd be like the boss zombie.

 

Mosquitos. At least here in the south.

 

Walkers don't run though, they shamble. So, would a zombie rhino run? I'm going with the smaller critters, because everyone needs to sleep sometime. A rat could just sneak up on you while you were resting. Heck, snakes a pretty stealthy too.

 

I still think even at a shambling pace, a cheetah would be terrifying. They have retractable claws!

 

Are we counting fantastic animals? If so, dragons FTW.

Are we counting extinct animals? If so, Tyrannosaur.

Are we only counting currently extant species? Then, humans, obviously. We're the scariest organism this planet has ever seen (and I'm including the Ebola virus in that calculation).

Great choices of animals. I don't know how I would be able to top this one.

 

elephant
gorilla
tiger

 

all the animals would be hindered by their sudden lack of speed.

but i think zombie mosquitoes would be something to avoid

 

Honey badger. No explanation necessary.

 

Zombie Magpies.
Or whatever your equivalent is over there. Bloody things are dangerous enough :/
Along that same line; pigeons, ravens, crows, peregrine falcons, pretty much any small fast flying thing.

I guess it's mostly densely populated pests you gotta worry about. Over in the US you guys have a coyote problem right? Feral cats too. On the other end of the scale, zombie bees would be terrible. You could kill them all, but then how do we pollinate all the flowers D: (Other than zombie butterflies).
