Stuck in pet moving situation

I am stuck here in jungle. its been 2 days i have been thinking how am I going to take these both ocelots back to my base.

---

The first thought in my mind was going via nether. however I didn't find any nice path in spectator world (world with same seed + gamemode sp). so pathing in nether is major problem. I will have to do in survival + Protect these kittens from taking any damage. So overall nether is risky place.

here is what I have thought

Path 1 (red path):

going from,

A -> B : sprinting with the cats till swamp.

B : get some slimeball and make lead so the pet ski can be done (Reference; Indicated by dotted line on map)

B -> taiga -> C : using the above water ski method get ocelots and wolves from taiga to home location

Path 2 (yellow path):

going from,

A -> B : use boat to go to swamp quickly.

B : get some slimeball and make lead.

B -> A -> taiga -> C : go to jungle. make ocelots do water ski till taiga. next let wolves + cats do water ski till home location.

Path 3 (light pink path)

use land to move all pets; no need to gather slime and make lead.

I am assuming it is going to take about 5 to 6 hours at max (If I do correctly). Which method is optimum? any other suggestions (no nether) would be good.
