Hey, other people have mentioned treat dispensers and balls so i thought i'd just tell you about one i make,
Get a toilet roll tube and cut it into rings, so basically you should be left with 3-4 rings then slot all the rings together, so they make a ball, but with gaps, so it should look like this ...
Put some string through it and hang it from your cage
If you fill it with small treats, seeds etc. (veggies don't work as well as there quite big and stick to the cardboard) then the guinea pigs will smell the treat and try to figure out how to get it out. Then when they get bored they can also nibble the tube
Another of my guinea pigs favourites is Kebabs ! get some string (thick string) , get there veggies, and thread the string through, i use an old turkey needle to get it through the veg, and once your done, hang it in there cage ! then they will have to work for there veggies, it keeps my pigs entertained for ages.
(Sorry no pics of this one :/ but i have a link to a video if you want)
Like others have mentioned, toilet roll tubes are almost a guaranteed winner when it comes to piggies, BUT DON'T FORGET TO CUT DOWN THE SIDE. You can fill with hay or just leave it as something to chew, mine walk through it sometimes 'cause there a bit weird.
Someone else mentioned this, but Primark bags, or any form of brown paper bags are great, if you just fill it with hay maybe a cheap towel or flannel something soft, they use it as a bed and also nibble it.
I try to vary how i make mine, either on it's side with the entrance as just the top of the bag or standing up with special holes cut in it. You can cut more holes in it to make it more like a play house that they can run through, but if yours are anything like mine they'll make there own holes ! haha.
Another thing my piggies like is just to chew on a plain scrunched up peice of paper (Doesn't matter on the size) also they like to roll it around and try and stand on it and stuff, they don't play with it all the time, but they do go back and nibble on it every now and then !
Now on to shop bought ideas...
My guinea pigs aren't a fan of shop toys and only like two out of the many i have bought, one being a treat dispensing ball that they roll around, i bought one with raised carrots and they chew on the carrots too
The final toy is just a scented chewing wood block, now my guinea pigs have paper and toilet roll tubes they don't use this as much but as you can see it was once much loved .
I hope this helped and you find some great toys for your piggies
