My cat, Bendi, would eat himself comatose if I left food out for him. And he eats so fast he gets the hiccups. Every time. (Which is adorable, but probably not a good thing.) He is also not yet 1 year old and is a big cat, so I knew I needed to do something and fast.
First I switched him to a less fattening adult food (his birthday is next month) and then we have been trying out cat food dispensers to slow his intake. So far his favorite is the PetSafe SlimCat Interactive Toy and Food Dispenser Ball.
He has a constant purr as he bats it around like an expert. It is the cutest thing. It has also slowed him down significantly and he appears to be on high alert to every sound in the house (as opposed to laying down – yea, he did that – while eating from his bowl.) He is always pausing and listening. When he is done, instead of hiccuping, he flops out in total contentment.
