I have no idea. I thought they were too big to fit in their mouths and a little too heavy to even attempt it but one time in the middle of the night I was awakened by the horrible sound of a golf ball being batted around the bathtub. It sounded like I was living underneath a bowling alley. I don’t even know which cat did it because by the time I dragged myself out of bed to investigate the cat was gone. I hid the golf ball after that.
Yep, they sure do love golf balls. In fact, I buy practice golf balls for our cats, just for toys. None of us humans plays golf.
After you clean out under the couch, go move the dryer. When we got a new dryer, we found out where our cats had lost all their milk jug rings. Both of our current cats will stop whatever they’re doing and watch me pour milk. There’s a chance that I’ll finish off the old jug and have to open a new one, and thus produce another magical milk jug ring.
Another fun cat toy are those foam hair rollers. I always take the plastic clips out of them and let the cats play with the foam tubes. They’re very lightweight, and move so very enticingly.
I went to Target yesterday and got a tube of “tough bubbles”. These are similar to the regular soap bubbles, but they toughen up after a couple of seconds. So yesterday evening I spent a few minutes blowing bubbles, and then watched the cats stalk the bubbles. Since we had the AC on, the bubbles drifted in the air currents, with two cats following them. Much better than whatever was on TV last night.
One of ours, Little Bit, is fond of billiard balls.
They’re a little heavy, but she’ll lie on her side and attack it until it gets moving and then she’ll get up and bat them around with her paws until she loses it in a pocket.
When she’s just laying on the table, we’ll slow-roll them at her to get her going and then she’ll just kind hug them with her front paws, start bunny-kicking with the back ones, and gnawing at them. She can’t actually get her mouth wide enough to bite the ball, of course, that’s what makes it so funny to watch. 
Hmmm…“tough bubbles”, eh? Wonder if my cat would like those too. Will have to check those out.
I can also vouch for the golf ball thing. I have an oak floor in my kitchen. The cat loves to swat a golf ball around in there. I think it’s the noise it makes.
BTW…a Swiffer floor duster will fold almost flat and is extremely handy for retrieving all manner of things from out from under stoves, dryers, couches, etc.
I can always tell when something kitty was playing with had the nerve to escape under something. She parks herself in front of the offending piece of furniture or appliance, and stares at me forlornly…all the while meowing loud enough to wake the dead.
And, you know—I’m sympathetic enough to the cause that I’d allow them a ball or two to play with (not a good one, mind, lest I be susceptible to a nasty slice-hook worthy of an abused range ball), but just my luck that it would be found underfoot on the eve of a nasty spill.
I’ve found an attractive flowerpot (in which to contain the balls) to be a suitable defense against such feline hi-jinks—so far. 
Thw Swiffer-handle will be armed a bit more closely in the future, nonetheless.
Tough bubbles—great idea. I’m sure they’ll love those. As are practice balls, since I’ve quite a few of those. I’ll try attaching one to a string today.
One of my cats developed a craving for my makeup brushes shortly after her was neutered. He was a rather large longhair Snowshoe and looked very silly carrying a pink makeup brush around the house. I kept reminding him that the operation was a neuter, not a sex change.
I have converted my double garage into a cat suite - carpeted shelves and ramps, a cedar climbing tree, lots of windows, their own couch, recliner and crib - and my office adjoins in the former shop. When I have the laser pointer out, only one of my furbabies has figured out that I’m controlling the “prey.” When the light goes out, 7 cats search frantically for it. Bill turns around and looks at me.
