"Your training begins now," he announces.  "Try walking quietly."

He is not used to having four feet nor how these feet behave but he can do obvious things like not stepping on crunchy leaves?

"That's better."  His tone is flat.  "But try something more like this," he demonstrates, "than this.  Feel your weight in your haunches, instead of your paws."

Kyeo doesn't know what that means but he will make an attempt to mimic the other cat's motions.

"You're improving.  Keep doing so while we travel."  And he leads the way, nearly silently.

Follow follow.

Tigerstar stops to suggest improvements to his form a few times.

"Russetfur, one of my warriors, and her apprentice Cedarpaw, began this dawn patrol with me.  Try tracking them."

.......sniff sniff.

There are a lot of cat scents.  There's one element which they all share with Tigerstar but not with him; there's another that they seem pretty split on and which he and Tigerstar both have.

Some of them are stronger than others, but there seems to be one more than one axis on which this is true.  Some of them are - sharper, than the rest, while others are bolder.

Probably being from this planet versus not, and then sex. No idea on the multiple axis of scent strengths. Is there... an axis of scent strength on which him and Tigerstar have every other cat beat handily... and along which he can identify third and fourth place.

It's totally the sharpness.

The next-sharpest pair have a trail heading off at - this - diagonal, but it's hard to tell which direction along it they were going.

...which direction would Kyeo have been less likely to have noticed them in some other way already if they were going that way?

One side of the scent trail goes off at an acute angle to the right of the line he and Tigerstar have been travelling in.  The other side goes back and to the left.  The road he crossed is to their right.

He'll try veering right.

Tigerstar follows without speaking.

For a while it's hard to tell whether it's getting stronger or weaker or if he's just going slightly off the path, on a moment-to-moment basis.  But then there's an especially muddy patch with some paw prints heading in the right direction.

Triumph! Stalk stalk.
