My piggies weren't that wild about fleece , if they had the choice between fleece and a bed of hay , they'd pick hay .
But fleece comes in handy in summer when you want a soft sleeping area without them cooking themselves in hay .
Or if you have a guinea-pig with an eye injury (hay poke) or a wound and you don't want to risk injury
-though they still need eating hay . You can buy solid blocks , use a hay rack or stuff loo roll tubes with hay to keep them busy. They need 24/7 access to hay.
There are petbags you can buy ( equine or dog blanket ones) that keep it all in the bag not your machine .
I bought a load of Ikea fleeces , about £1.80 each. Rough fleece wicks the pee better . You need something like newspaper or puppy pads under the fleece .
Use an unscented detergent , they are very respiratory sensitive . No fabric conditioner .
Just to warn you though . They are the messiest little animal EVER . They don't smell but the hay does and it gets everywhere .
Boars IMO are tidier than sows .
For my water bottles , I made a holder from an empty plastic drinks bottle , cut the base off , part of the neck, fastened to the outside with cable ties , with the neck pointing down. Then the water bottle just slipped into the plastic outer with the tube through the bars .
Much easier than springs or those wires .
You need to change water daily .....and they often don;t drink it
