Despite only being in the hotseat at Tynecastle for two months, knives are already out for Cathro given the bumpy run of results and performances he has overseen since taking over from Robbie Neilson.
There are mitigating circumstances that he could have done without but there is a myopic element amongst both fans and some members of the fourth estate who refuse to take any of that into account.
Yesterday's 4-0 loss at Celtic was disappointing if you were a Hearts fan.
Especially when you saw your team face Scotland's best side having a multitude of injury worries, still suffering from the poor striking recruitment done by the previous manager, new players still trying to gel and your best man - Arnaud Djoum - away on African Nations Cup duty with Cameroon.
Radio Clyde journalist Hugh Keevins took to Twitter last night to proclaim this side the "worst Hearts team he has ever seen" - failing to take into account Gary Locke's team (albeit hamstrung by administration) and the Seith/Ormond/Moncur/Ford sides that presided over Hearts' worst spell in the late 70s and early 80s.
Others have made withering pops too. BBC's Tom English wrote on Twitter that "Hearts have major problems" following the loss to Celtic.
By that yardstick, so too do Rangers and Aberdeen who like Hearts have received wallopings when they've visited Parkhead this season, while Partick Thistle and St Johnstone must be in title contention having only lost narrowly there.
A risible argument but one that highlights the holes in cases presented by 'expert pundits'.
Cathro has effectively been asked to rebuild during mid-season when summer is the time for such work.
He has made some new signings during the January transfer window and they will take time to settle in and gel with their new team-mates.
Pre-season friendlies would be the ideal time for all of that but they're going to have to do that the hard way with competitive fixtures from the get-go. Something the experts would do well to take into consideration.
Like his predecessor, Cathro will also have to bring in new blood on a limited budget. Owner Ann Budge will not be breaking the bank to bring in the top quality that both manager and fans would love to see.
History shows that every time Hearts have tried that, near financial ruin has been the end result years down the line.
A year's time would probably be the most appropriate junction to stop and have a look at how he's been getting on.
By then he will have had time to bed in, assess the squad properly, bring in new faces and get them settled in with a solid pre-season.
And unless the team are languishing at the bottom of the league with relegation a certainty, then it is likely he'll be allowed to continue as Budge and Director of Football Craig Levein have consistently shown signs of not reacting to knee-jerk nonsense spewed forth by others.
Sadly, hiring and firing managers on the tiniest of whims has become common place in football both north and south of the border and it seems we will continue to have morons demanding their pound of flesh yesterday.
British football used to laugh and sneer at clubs in Italy and Spain hiring and firing managers at the same rate Homer Simpson consumes doughnuts.
We have no excuse to look down on our Latin cousins now as even they are looking at our managerial casualty rate with bewilderment.
Imagine if such a culture had existed during Alex Ferguson's first four years as Manchester United manager?
In fact there were some United supporters who wanted the aforementioned culture put in place especially for Ferguson.
One is reminded of the yobbish Man United 'fan' who screamed into a TV camera that he wasn't going back to Old Trafford until Ferguson was sacked.
You wonder if he could remember the way to the ground when Davie Moyes had his first game in charge decades later.
An embarrassing 5-1 thrashing to rivals Manchester City in 1989 had the knives out for Ferguson.
Yet Bobby Charlton - a United board member back then - had Ferguson's back and assured fellow directors that their patience would be rewarded.
It was and then some as Ferguson carved out the club's greatest era.
Another example is Brian Clough at Nottingham Forest. He took over a club in the doldrums and with his own reputation on the line after failures at Brighton and Leeds.
Everyone remembers the League Title and two European Cups he would guide Forest to but it a sticky three years had to be endured first before the rewards came in.
Under today's "I want success and I want it last week" culture, can we honestly say that both - who would become managerial legends - would have received the same patience from their board of directors were they in their respective club's dugouts now? It is doubtful that they would.
Cathro deserves the same breathing space that was good enough for them.
He might not come even close to matching their achievements or achieve a fraction of their success.
There is a chance that Cathro's reign as Hearts manager could end up in failure.
Either way, he deserves more time to try and prove his worth.
Regardless of what the eventual outcome might be.
