Bertie is real bad about inhaling her food. I used to free feed and it worked fine until Bertie went to the vet and had all of her surgeries. She had the cherry eyes, soft pallet reduction, stenotic nares and spayed. When she came home she acted like she couldn't get enough food or she was starving. I got her a slow feeder bowl and that wasn't worth buying. She won't eat out of plastic and the stainless steel one just had a big trough around the outside part of the bowl and a big bump in the middle. I got rid of it and I bought an Omega Portion Control Ball. It is made out of glazed porcelan and it helped somewhat...so now I have two of the Omega Balls...a small one and a large one. They are both in her bowl...they slowed her down a little bit, but she can still eat pretty fast.
