Motivation and dedication are still high!
I’ve managed to complete the schematic and PCB, get it sent off to oshpark (my favourite PCB fab!), get them back, and solder them up, phew. I went for oshpark’s 0.8mm board thickness in order that my stacking heights would work inside the case, so they took a little longer to arrive than normal.
The schematic is below (click to enlarge). It’s quite simple and comprises the following:

The base station is the handheld unit I’m going to use to communicate with the collar to work out where the cat is. Currently I’m using a CC1125 development board. More about that here.
The idea is that the base station will mostly live at home, perhaps in my loft (to get decent range) and I’ll be able to communicate with it from my living room via Bluetooth from my laptop. It should also be portable because if Buttons goes miles I want to be able to take the base station out and about to track him remotely.
I’ve finally finished the CatTrack schematic, hurrah!

As a reminder, my plan is for the collar to work thus:
