Fritzlein has moved:
21s Cd4s ed5s ra6s ra5s
with a goal threat preventing us from immediately capturing the camel

I'm looking at
22g Cc4s Re2w cg4w Dh4w
blocking out the silver e and threatening a capture on f3. Silver can respond by flipping the d3 Cat. I think gold can gain one or two rabbits in the ensuing tactical battle.

My reflex answer would be to strongpoint d3 with:
22g Cc4s Rc2e Db1n Ra2n
Notably Silver cannot put the camel on f3.
It might get slightly difficult to slide between sides, but if Silver comes and protect f4 with phant, we should be able to free camel by having the horse on e3 soon.
Meanwhile we retain our threats on f3.
On the other hand, Silver could try to goal attack in the west, but that seems doomed to inefficiency.
EDIT: In fact that's a *bad* idea:
22s He4en me3e Ee4s
is feasible since if we take horse, Silver has
23s Ee3nw xx *without* taklng camel
and the camel is lost on the following move.

The first, third and forth step look good to me.
There are some choices for the second step. If I analyzed correctly (thats a big if!), the elephant does not need to be blocked out. Silver's f6 trap is undefended.
Options for the second step include, Cc3w, Ra2n, Ra1e, Dc1w.

Without Re2w in 22g, I have silver respond 22s Cd3s ed4s Me3e ed3e.
Not sure how to exploit the unprotected f6 because capturing the cat there with either caMel or Dog leads to its own capture, sacrificing the exchange. Taking the g6 rabbit instead seems to lose the Dog at least.

I thought we might win m for H with
22g Hf2n Hf3n Cc4s Re2w
but something like
22s Rb4e cb5s de5n he4n
defends.
22g Cc4s Re2w cg4w Dh4w
22s ed4w Cd3n Cd4n ec4e
23g Eg3w Ef3e cf4s cf3x Rd2n
23s Rd3s ed4s Me3s ed3e
does not seem enough.
22g Cc4s Cc3w (or some other step) cg4w Dh4w
22s Cd3s ed4s Me3e ed3e
23g rg5n Dg4n rg6w rf6x Dg5n
23s de5n he4n he5e hf5e
24g cf4w Mf3n Mf4n Rh2n
seemed appealing but actually not after
24s ce4n ee3n ee4e
And yeah,
22g Cc4s Cc3w cg4w Dh4w
22s Cd3s ed4s Me3e ed3e
23g cf4n Mf3n cf5n cf6x Mf4n
fails to
23s he4w ee3n ee4e rh6w
Ah, and actually, after
22g cg4w Dh4w Re2w Cc4s
silver can use the same goal threat trick with
22s Rb4e cb5s cf4n de5n
Hmmm

Ouch. Somehow I feel it's important to keep silver from pushing our M->f3 with his e->e3. I can prevent that only in this line continuing with
23g Cc3w Me3s he4s Dg4w, without immediately giving up the R on c4.
Tricky tactics follow but I see no advantage for gold.

Actually, I really liked this variation until I got to the end of your post and found: 22s Rb4e cb5s cf4n de5n 
I'll propose an alternate move where we can sometimes can get positions. Hopefully I didn't overlook a key move:
22g Cd3w Me3w he4s Dc1w
22s Md3s ed4s de5s de4e
23g Hf2n df4w Hf3n Cc4e
23s Re2e he3s ed3e re7e
24g Cc3w Rc2w Md2w he2w
The position will devolve into an unclear mess.
22g Cd3w Me3w he4s Dc1w
22s ed4e Md3n ee4e Md4e
23g Cc4e he3e Me4s Cd4s
My biggest problem with this variation is that we can’t rotate our f2 horse out and our dog is buried on h4. But the frame should at least give us a slight advantage.
22g Cd3w Me3w he4s Dc1w
22s Md3s ed4s he3n ed3e
23g Cc3e Cc4s Db1n Db2n
Our western pieces are all awkwardly placed and Fritz might try another f3 blockade before we can get our western dog and camel onto strong squares. Fortunately, we may also be able to exchange rabbits in the west, and with only 14 pieces per side his blockade will be weaker.
We can avoid the previous variations by blocking the d2 square:
22g Cd3w Me3w he4s Re2w
22s ed4e he3s ee4s re7e
23g cg4w Dh4w cf4s Dg4w
is a winning variation for us, so Fritz would have to put his horse on f3:
22g Cd3w Me3w he4s Re2w
22s ed4e cg4w he3s ee4s
23g Cc3w Md3w Cc4e Cd4s
23s de5e cf4e df5s re7s
I think this is a decent variation for us. And I think we can get away with an even sharper move to threaten the c5 dog:
22g Cd3w Me3w he4s Re2w
22s ed4e cg4w he3s ee4s
23g Md3n Md4n Cc4e Cc3w
23s ee3n Cd4w ee4w hf3w
24g Re1n Hf2n cf4w Hf3n

I am still very short on time, and did not even look at the variations in chessandgo and Adanac's posts yet, but I would like to point out a possible move:
22g Hf2nn Cc4s Dc1e
The idea is that if the camel is thrown on f3, at least the horse is out, and we can play on f6 with views on using the h file for pushing our h2 rabbit.
Short example:
22s cd3s Ed4s he3w Ed3w
23g Hf4n rg5n Hf5w Mf3n
23s He4e Ee3n mf4n Ee4w
(or 23s He4ee Ee3n Re7n
24g Hg5w Mf4sw Hf5e)
24g rg6eX Hg5n xx (rh5e Dh4n)

After more thought I realized a couple of things about my suggested move:
1. It would be more logical to play 22g Cd3s Me3w he4s Dc1w because it blocks out the e2 square for the silver horse.
2. However, Fritz can now safely keep his horse on f3 due to the blockade around the g4 square (this works in response to any of the 3 moves that I've suggested: 22s de5s de4e ed4e he3e.
We still have some play in this position. For example, we can push the horse back to e3 while moving our own horse onto the f3 square. However,, I find that it's difficult for us to build any sort of advantage with this whole variation.

Yes, I like this move now, but I assume you meant Dc1w rather than Dc1e?
We can easily get our horse into the northeast and eventually clear a path for our h4 dog to escape. And our dog can seize the b3 square before the silver dog gets there. So far, this looks like our best hope.

Yes Dc1b1. I think I'll revert to this notation from now on, I more seldom misuse it.

I don't get it, there is the H on f4 and not the c?

23s He4e Ee3n mf4n Ee4w
(or 23s He4ee Ee3n Re7n
24g Hg5w Mf4sw Hf5e)
24g rg6eX Hg5n xx (rh5e Dh4n) |

It's an interesting possibility, but after something like
22g Hf2n Hf3n Cc4s Dc1w
22s Cd3s ed4s Me3e ed3e
23g Hf4n rg5n Hf5e Mf3n
23s re7e de5e cb5w Rb4n
I'm not sure whether we really have a good position. If we attack M+H around f6, feels like silver can hold to f6 while he's fine on the west, and has H to f2 prospects of our caMel leaves.
