Basically im looking at a friends cr-v and cant come to a logical expilination as to why its doing they. It struggles to accelerate uphill and especially from a say a stop to 30mph. No idea whats wrong with it but he did say he had the cat changed a while back because it got plugged after using seafoam.
Hond CR-V High RPM'S When Accelerating

Another car death due to unrequired and verbotten service!
The range of things it could be is relatively large. Are there any more symptoms than lack of acceleration? Is the engine going through the revs smoothly? How many miles does the car have on it?
First thing I would do is check the spark plugs, perhaps the seafoaming fouled them.

Many people have successfully and continue to successfully use Seafoam. Just because a few people mess their cars up doesn't mean the product is bad. When you release a product with any ability for people to mess up the usage, it is guaranteed that people will.
However, Seafoaming is known to foul spark plugs and I would always change the oil immediately after the treatment. I would also only use the through the intake method.
@ OP. Also, was the Seafoam in the oil? Or the intake vacuum method?

Depends on how poor the actual performance is. If you have stepped out from a torquey 6 or 8 cylinder vehicle, you may feel the CR-V is struggling to accelerate up a hill. Test drive a similar model somewhere else, and compare.
Mechanical issues that will degrade the performance to such an extent will likely throw a code. Perhaps a stuck e-brake?

Well, the 2.0 or the 2.4. The 2.4 is 2002 and later IIRC.
No OBD codes?

I've never owned an engine that "needed" Seafoam. A properly maintained engine never should.

High performance and blown engines accumulate carbon if driven around town. Seafoam finds a useful application in such engines. Ferrari would take cars that are performing poorly due to carbon buildup and run them full throttle on a race track to clean out the carbon. These Ferrari's were properly maintained, just they were driven in conditions that allowed for the buildup of carbon. But yes, the average production car does not need to be seafoamed.

My solution for that (my one car has a rather warmed up 302 in it) was the occasional (OK, it was a lot of the time) spirited drive. it also saw trips to the drag strip, and the like. A performance car should be driven accordingly every once and a while to "clean it out". This doesn't require Seafoam

Before throwing in "da bones" about guessing what's causing the problem (or leading to the issues), consider doing all the educated checks first:
(1) what/why the cat was replaced at the first place? was it plugged? throwing in a lazy code?
(2) what's the mechanical maintenance history of this vehicle? when was the last valve adjustments done? spark plugs pulled and inspect? what's the condition of the spark plugs?
(3) was the brakes dragging?
(4) was the trannie shifting properly (m/t or a/t?)
(5) any occasional/stored CEL codes recorded?
(6) trannie (assuming a/t) fluid level? was it stuck on "2nd" gear instead of "D" when shifting? (I had my dad's 7th gen civic doing this w/o knowing and the upshifts from standstill was terribly slow BTW).
then we go from there.

Dont you think the I/M ingested HydrogenPeroxide and Alcohol mix or just plain Water and Alky would be safer? Or, worse, the old Kerosene soak through the plug holes overnight (a flathead favourite) ?

Change oil and the plugs... I have owned CRV's and they are not known for quick acceleration.
You could also find a good mechanic and have him check it out.

So high RPMs while accelerating is bad?
What is going on with that car?
