it cant be a mole as there apserluteveracious predetors . is it some kind of rodent i wonder like a rat or a rabbit ?

It would have to be a very small rabbit, lol. Don't like the thought of it being rats but what else makes holes that size?

youd of thaught they would just eat them above ground when its dark as it goes realy . strange one . look round the garden in the edges for rat scat etc or get a rat trap . they love peanut butter not cheese ,

In northern Arizona, those would be voles.

Thanks everyone, will get a trap,peanut butter you say?
Could be a rat, we've got a huge farm next door.

i thaught voles were preditorey to

Voles are essentially small mice, Np. They take a few insects, when they can catch them, but they mostly dine on roots, seeds, and tender greens. 2 inches is a bit big for vole tunnels, but also rather small for rats. Here in southern Arizona, ground squirrels would also be a candidate, but I don't imagine that there are many of those in the UK! : )

i think most if not all small vegitarians substitute spiders and small insects as the veg isnt easy to break down hence cows etc having 4 stomacks . you learn something every day .rats will make a whole just big enough to fit threw just like birds and other burrowers for there own protection . theres plenty of prary dogs round banham zoo inside and out . they can live as a sociaty in up to 4,000,000 which is why the ranchers hate them . not only eating what there cows do but breaking legs etc . a trap will soon find the culprit . i actualy sore my large alsation get threw a biggish cat flap which was impressive .

Voles certainly eat tree bark as they ring barked my 12 foot cotoneaster & it fell over. They started on another shrub until I surrounded it with chilli pepper - no trouble since.
NP voles mostly eat veg - fruit, nuts, berries, bark, pine needles, tree roots & insects. etc & field voles eat mostly grass. Voles holes are usually smaller than 2" too. Its a puzzle. Cozzy you could try surrounding your cabbages with chilli powder as its would deter most things!

be interesting to know what it is .

voles are omniverous much like ourselves then . interesting .
