What is this rodenty thing?

[Tweefutom]

The dog started playing with something in the sitting room. Then the something started squeaking and I panicked shooed her outside.

This was the rodent she caught. What the dickens is it? DH thinks it’s a mouse, I’m afraid it’s a baby rat.

Rat I'm afraid

wood mouse if it has kangaroo-ey legs

Looks like a baby field mouse to me

It really doesn’t look like a rat to me and I shoot or trap them frequently round my hen pens.

DH says bank vole

Look at the size of the blades of grass. That is too big to be any kind of mouse.
Baby rat I think.

"Looks like a field mouse to me."

Had to laugh at this. In my experience, whenever anyone finds a mouse in their house, 9 times out of 10 they describe it as a field mouse, as if there is less 'shame' in having a field mouse in the house than a house mouse.

Having bred rats I don't think that is one. Back legs too long and nose not Roman enough. But wet as it is, at that angle, I can't be 100% certain.

Google photos of baby rat, field mouse, etc and see which you think it is. I can’t see the photo clearly enough to tell, my phone is not the best. It’s not a bike as it’s nose is t long and pointy as far as I can see? I’m 100% sure it’s not a house mouse.

A “bike”, stupid bloody phone, a VOLE. Why does autocorrect not know that word ffs.

Oh it/s so cute!!

(I have no idea what it is).

I reckon field mouse, though depends on ears (mice have big ears) tail is too long (legs not seeming right) for a rat.

Not shrew, mole or vole. Voles have very short tails & very different colour, so can't be vole.

D-Cats bring home a lot of rodent body parts; I know my UK rodents.
That said it does look gerbil like, but I don't think they're common in the countryside.

Probably just a Mouse.
Do not put poison down!!!
Anything that tries to eat the dead vermin will die a nasty painful death too, so yours and your neighbours pets will be at risk.

Not a bank vole. They're very squat and squishy looking. And outrageously cute. We had them in our garden over the summer as well as a nesting field mouse and the field mouse was far more gangly like the op.

Going by the corpses (and live runners) from DTwatCat #1's Mouseageddon 2019 Season, it is a Field or Woodmouse. There is a noticeable difference between them and a house mouse.

And yes, bank voles are a reddish brown.

Mouse

Field mouse?

Eek! Why do you think your house is rat infested? Didn't the dog find it outside?

He’s far too large to be a baby mouse. Mummy mice are only tiny themselves aren’t they.
He’s gorgeous, though. I’d be snuggling him if I found him.

FFS adult mouse not mummy mouse.
That’s my nephew he calls all adult animals mummy ones

Rat, definitely a rat. Did your dog bring it in from the outside?

DH says field mouse - hope it recovers. Please consider humane traps, then you can release them in a different area. Poison causes a slow and horrible death.

If the tail is hairless and ears are small, it's a rat.

Field mice have hairless tails... mice have nice big ears.
The body shape is different mouse v. rat, the leg geometry is different, this is why rats often bound but mice only scurry.

Voles have little ears but short tails & very different fur from OP's critter. Voles also scurry.

Rats are chunky & robust build. OP's critter is skinny build & not chunky.
