Also remember how far Squish has come -- I remember not long ago that he couldn't go off leash at ALL without a giant affair of running away and not being catched. It's exctremely cool that he's a lot better now.

It's really easy to fall into the mindset of being fair to both of them, but really, it's better to give them what they need, rather than be fair. If Spike needs more off leash running, give it to him. Squish will be happy if you let him smell interesting things.

And yay for Gus cats found in the wild! I bet that cat didn't have weird multiple length fur though. :)
