what size should i get for my little fella?

idk not a small of course. but id say a medium but i dont know the sizes( i would have to see it.)

Wobust or Senior for sure

actually, id say get a large. because ur suggie might wanna pile in at the same time or something.(just to b safe)

Senior is the perfect size!

anyone use the thing that files their nails in it?

i use the nail file insert for mine....it kinda files haha. It doesn't replace trimming their nails though, at least for mine.

I love the trim track! I haven't clipped nails in a few YEARS! I did have their initial clipping done at the vet when I had their well checks but the trimming track has always maintained them. The only downfall is if they don't like the wheel, which we see around here occasionally.
