Catfolk have an exclusive Bloodrager archetype, the awesomely named Prower at World's End.
Maybe that might spark some ideas?
If you want to really focus on dexterity go with an urban bloodrager and aim for something like slashing grace, starry grace or fencing grace.
If you want to attack with strength (perhaps for the greater damage, perhaps because you don't want to spend the feats) the standard bloodrager works, maybe with primalist to drop a less-useful bloodline power. You can afford some of the catfolk racial feats this way if you like too.
The abyssal bloodline is the best for damage for str-based, aberrant or black blood lets you stack up bonuses to reach, arcane and destined are good on defence.
There's a guide to bloodragers here. You might know that already, but I post it in case you didn't =)
If you go Urban Bloodrager and a Dex based build, consider dipping into Swashbuckler. Weapon Finesse will help you pick up Fencing/Slashing/Starry Grace. You might take the Inspired Blade archetype, especially if you can afford Int 12 or better, for Weapon Focus too.
The guide is incomplete.
I still recommend STR build.
You can not mess up a Arcane bloodrager unless you really try.
I would go with one of these 4 bloodlines:
Arcane- 20->50% miss chance when raging makes you a strong frontliner. Add in the DR this bloodline has all the juiciest Layered defenses you could want.
Aberrant- Immunities, reach, staggering critical... Ability to access Aberrant Tumor for a bodyguard familiar...Strong stuff. IMHO the strongest tank builds are Aberrant followed by Arcane. I played a level 20 version with 13 immunities, fast healing 11, effective health close to 400...He was a mini terrasque.
Destined- Luck bonuses...Fits a cat being lucky.
Abyssal- this is THE natural attacks bloodline. If you go natural attacks.
If Primalist archetype is available then take it. Always.
I personally love Spelleater but many do not. But it is an archetype that can be built around and completely optimized out to be rather cheezy.
