I got this bowl because my cat loves to eat fast and then throw it all up moments later. The first time I gave this to her she slowed down and I think she enjoyed the challenge of getting the food that was caught between the fish out. She has not been throwing up after giving her this bowl.The bowl was a bit bigger than I expected which was a plus. It’s quite heavy and difficult for the cat to move so it will stay in one place and not make much noise.I recommend this to all my friends with fast eating cats.My cat has no teeth and also loves to inhale his food. We got this and it’s helped so much! No more scrambling to clean up before work after he gets sick from eating too fast.The product is good. But our cat doesn’t like it. So I’m back to monitoring his eating so he won’t eat too fast.The dish is lovely. The swimming fish are cute. It’s a bit bigger than I had expected. Perfect for a cat or small to medium size dog.But my cat hates it.I won’t return it. I will donate it to my local shelter. Because someone will want this, and get good use out of it.My cat definitely slowed down eating from this, but she struggles getting her face into the entire bowl due to the height of the barriers. I worry about whisker fatigue with this bowl. But if your cat doesn't have that issue, it should be great!I overall liked this product. However, when my cat tries to eat around the bumps, she can move the bowl all over. So she has to chase it all over the living room. It would be nice if the bowl had anti-slippery material on the bottom rim so that this didn't happen. Instead, I am going to have to buy an anti-slippery mat.We decided to try this for wet cat food. We found both cats are eating way too much way to fast and throwing it up. Since we started using them about a week ago, we haven’t found any food throw up to clean yet. It is easy to clean IF you’re using a scrub brush, and it works in the dishwasher. We keep food closer to edge since middle seems higher.Our 5-year old cat started throwing up weekly over the past 2 years due to eating a little too fast – this started when we adopted a younger cat who would push the older cat away and eat her food. The younger cat eventually stopped her aggressive behavior and actually stopped eating much as she’d rather play or be near me. I’ve been feeding both cats 5 -6 tiny meals each day, but the vomiting continued. Our Veterinarian recommended slow feeder bowls for both cats, suggesting the younger cat who was disinterested in food and low in weight might also benefit.Both cats hated me for 2 days and ate reluctantly and minimally, then they each grew used to the new bowls, and seem to actually love them. Our older cat has not thrown up once since using these bowls, and I’ve increased her food to full meals at one sitting – what a miracle! The younger cat apparently enjoys the effort it takes to eat from her new bowl as well and has even gained weight! I’m happily surprised by this!I should note, neither cat likes to use their paws to retrieve food, so I only put food in the 2 outer rings, as the ‘fin bumps’ get higher toward the center. Also, I feed both dry and wet food, and using a spoon, scrape the wet food off onto the outer ‘fin bumps’. I soak the ceramic dishes daily as they become messy from the wet food, but so does any bowl.I was skeptical such a basic idea would stop our cat from vomiting, especially since small feedings over time didn’t work, and I was almost positive our finicky girl would eat even less if the effort were more. I am so happy to be wrong on both counts!I rarely write reviews for anything but this bowl made my cat stop throwing up. She used to throw up 3 or 4 times a week. She would eat so fast and wouldn’t chew her food. I tried everything. Switching food. Soft food. Different bowls and nothing worked until this! My only advice would be to get a rubber mat under the bowl because it will slide around on hard surfaces. For the record I am not being asked or paid to write a review. When there is a great product it deserves its praise. I hope this helps people on the fence about buying!My cats tore apart silicon slow feeders or could flip them, whereas this one is the dream. Will never need to replace as it’s sturdy and weighted, plus is slick and stylish looking being white porcelain. Super easy to clean too 10/10 wish I’d found it sooner. I have two cats and they both can enjoy it at the same time
