I'm a fleece fan, but also a Vetbed fan
both are good.
But in addition I like to have trays for their hay with Fitch in it, and this is where they do most of their wee's (skirting round the hay in the middle of the tray
The fleece I use is made into a quilt, with a waterproof washable material at the bottom, polyester wadding in the middle, and one layer of fleece on top. Quick to dry, convenient, stays in place well. I made this before I came across Vetbed.
Vetbed comes in two types, one with a rubber waterproof backing and one without. I like the one with the backing, but both have their merits. A good combination for Vetbed may well be one without the waterproof backing, wicking the moisture to a towel underneath. I'm yet to try that, but if I was starting again I would.
So my cages have Vetbed, Fleece and Fitch, all in different areas, and all with their useful functions.
I've also read of other fleece fans who like to have a tray of litter and hay, for the same reasons as I do. It is a good combination and makes the fleece easier to clean when the hay is separate and stays fresher longer due to them doing their wee's in the litter. The litter really can be very useful to have, and being as it's just in a tray it doesn't cost too much to replace as you are not using much per change.
So in regards to fleece and vetbed: Vetbed can be cut into the desired shape without the need to sew. It can be either on it's own or with an absorbent layer beneath, like a towel.
Fleece is best is sewn into a quilt-type thing in my opinion to negate the need for clipping it into place over towels etc. It's just easier if it's all in one, but this requires sewing. But then some people prefer the separate fleece and towels. Personal choice, but you do need to keep in mind that fleece needs SOMETHING underneath it, and something to hold it in place if it's not sewn into a quilt.
