please help out of ideas - cat sick

[McPrice]

i have 2 cats one female 4 years old and one male 3 years old, both we rescued from kittens at the rspca. we have a problem with the male and if we cant get a handle on it we are going to have to get rid of him.
he is a very affectionate cat who doesnt go out much (unlike our independant female cat) he loves to spend his day on a lap or a sunny windowsill.
the problem we have is not a new one hes done it since he was a kitten. he sicks up after eating. its gross. he eats without chewing then goes somewhere high and projectile vomits everywhere. the clothes airer or a windowsill are his fav's as is the stairs. we have taken him to the vets and they have done tests -they say nothing medically wrong just some cats do it
he has done this for 3 years.
when he was 1yoa he was diagnosed with f.l.u.d which means he has to have medicated food.
we give him little and often food which is ok but he steals food and then is sick - sometimes hes even sick if he eats too quickly the small amount.
he frequently steals our other cats food - she is a grazer and happy to nibble and return later.
it feels like i have tried everything - i clean up his puke practically every day. its gettin worse as i now have 3month old and i forget to shut and lock kitchen at times (he can open it) hes been sick on the babies bed this morning and his drying clothes yesterday. any suggestions??

we have tried the following
. the cats get fed in different rooms
. special bowl to slow eating
. dry and wet food - hes on hills c.d dry
. feeding outside and not allowing i until 1 hour has passed. he screams at the patio doors
. putting extra water in his food
. putting his bowl on a higher level e.g pile of books
. shutting him out all rooms apart from living room . he darts past my legs and i have to catch him everytime the door opens. not easy with a baby.
.putting a cover over female cats bowl but that stops her from eating too

We have a cat who does this. The trick in our case has been to let him eat lots of small meals. If he is without food for any length of time he over eats and then is sick. The utility room is now the cat room. He's only allowed out if he's eaten and kept it down. He always has food available, then he doesn't feel the need to overeat. Its not 100% but mostly works.
I've also invested in a carpet cleaner sighs

actually we did try limiting his food but it didn't work... he is better always having food available.

thanks for reply. not sure this would be possible due to medicated food and having 2 cats. what happens when i go back to work?
