Yes, right the one with the handle are meant for horses and you could not use for a bird. Jolly Pets company which who is Horsemen's Pride has widely changed things over the years. I am or have been highly sadden by how they've changed. Oh, they say for the bird industry there are not people who buy from them and now there are even less. I have noticed the jolly balls I buy are not near the quality they once use to be, because now they are for outdoor play ... the way they are finished they have scratches and often the insides are not as nice inside as they use to be. Anyone who gets their balls from me and are scratchy, well they come that way to me, I put no scratches on them myself. I am so disappointed with their finish on them. There are a few here and there that have a fairly nice finished look.
Then the big whammy when they discontinued the 14" size jolly balls with the holes in them. So I would have to purchase their "Push-n-Play" ball which has no holes and I have to cut out all the holes myself. They simply would no longer do that part.
As for the 6", 8" & 10" balls they use to be called "Ferret" balls or "Critter" balls and they were always beautifully finished, no longer and now they call them "Teaser Balls" which have the little green ball inside and are meant for Dog play. So I'd have to buy the Teaser Ball and remove the inner green ball, no big deal they are fairly easy to take out except on the 6" balls because the holes in the 6" ball are quite small and hard to get the collapsed green ball out through the hole. I even asked Jolly Pets when they would sell me the 6", 8" & 10" balls to not to put in the green ball, but nope they send them to me like that anyway. My son's dog loves playing with the green balls I give her and give them to my sister's dog who likes them too and they can chew on them too!
The 14" balls - I think I was about the only one out there cutting out the holes in the 14", I think one other person who was doing it too but don't think any longer. So you maybe highly unlikely at this point in time to find them with the holes cut out of them. Having to cut out the holes in the 14" ball had really been a huge extra step for me to do. There was a lady who recently had bought all 11 of 14" that had had left in stock so I had not previously cut out the holes so I had to get all those done then shipped them off. I can say this, I certainly have more room in my shop!!
I am considering on posting my PDF on how I cut the holes in the 14" balls in the DYI forum so if anyone is interested. It does not have every nitty gritty detail but if you understand things, it would be helpful. I had one gal on here who asked if I would not mind to tell her what I used or how I did the holes, so I sent her the info.
