Is a cat carrier safe?

Cat carriers are great for piggies! I'm eyeing a top opening one.

Should i put fleece on the bottom?

I do. I have a fleece baby blanket I fit into the bottom.

thank you

you might want to clean it out he might be afraid of the cat smell

Would it be alright to not put any fleece or anything in it if i was just taking them somewhere in the house/yard?

If you're just using it as an elevator method, then I don't see why not having fleece in there would be a big issue.

Thank you!

All right, so my cat carrier has a plastic top, plastic walls, plastic back and a plastic floor, but the front door is made out of metal grids that are not 9 by 9, so my question is, would the piggies inside get their heads stuck in the bars?

Can you meaure the grid holes or take a picture of them next to a coin (for size referemce)?

All cat carriers I saw when buying mine had tiny front door grid holes.

The issue isn't whether it's 9 x 9, it's how large the spaces are. It just so happens that a 9x9 grid works ok for adult guinea pigs, but the grid is 14 inches wide. A 9 x 9 in something three feet wide would let a small dog through, and in something 9 inches wide, a hamster might not fit.

Measure the distance across the holes in the cat carrier and see how large they are.

I have a few different kinds of cat carriers for my guinea pigs. None of them have grids large enough to fit a guinea pig's head in. In fact, the openings are smaller than cube grids.
