The cages, which have been placed around the universities campus, completely cover the area surrounding the warm air vents near the college buildings.
Students say they are "disgusted"by the cages, saying that the move shows a lack of love and compassion for the less fortunate.
@cardiffuni how can this be acceptable in this day age. Despicable. I am ashamed. http://t.co/98pdm42uJ8"A cold, ugly barred cage had been fixed to one of vents" Cardiff student Lewis Hopkins wrote on his blog.

"I had noticed the winter before that these vents bellowed a comforting pocket of warm air, which from time to time was occupied by the homeless. They never caused any trouble, never littered nor gathered in groups. They were just content with finding a warm place to sleep at night"
He also said that the cages made him "feel disgusted and ashamed" of the university.
However, Cardiff University said that the cages were installed for reasons to do with public health and safety.
"The area covered by the safety grilles are not hot air vents but boiler flue vents that can potentially produce products of combustion - diluted amounts of carbon monoxide being one of these - as part of the diluted boiler flue gases," a spokesman from Cardiff University said.
My alma mater, @cardiffuni, has installed an anti-homeless person cage by a warm air vent. You stay classy, Cardiff. http://t.co/Or83hwHUMK"These vents are considered safe in normal use due to the type of flue dilution system being used but there could potentially be an increased risk if people are sleeping right next to the grilles for very long periods."

Cardiff University's move comes following the revelation that well to do London boroughs were installing 'anti homeless spikes' in order to deter homeless people from seeking refuge there.
Outrage against the spikes led to protests on social media websites, which eventually forced the council to remove the spikes.
Remember, a person down on their luck is not a person. You are a thing to be shuffled along, kept out of sight, and stay at the soup kitchen you useless beggars.
Becoming homeless happens excessively easily. Whats worse is it takes a lot of hard work to get back onto your feet into this paradigm we exist in. Hardest of all is to find someone who will give you a chance, an opportunity to make their life better. Lmfao!! Your colours come forward then. Ive been there twice, first time didnt see it coming, second time I 'was' a student. Rare is the person to extend generosity and trust to another, especially if on the surface that person seems dirty or in shambles...as that means Im a sketchy murdering asshole (the latter part is true enough).
Chances are the dude that will 'flow a well for food' actually would prefer a day or twos work w/shelter vs a handout.
