Hi Biblofilter,
Congratulations with your birthday.
Don't worry about the age, there's at least one over here who's older than you
To get the most out of the Feral Bobcats I think you could use a "finesse" strategy, like for example :
Design your spellbook around a "moving" mage, not a "stationary" one, this implies him to be more of a support/ranged/control mage than a melee mage.
Use your mage as bait to draw in the opposing mage ( works best on a melee opponent obviously )
Each round, ( try to ) move your mage out of a zone containing one or more cats into an adjacent zone containing another ( preferably guarding ) cat.
This way you can move into the protection of a creature with a Defense, while at the same time setting up the Charge effect of the other ones.
Since "moving" will be key to this strategy, Force Push fits in perfectly and thus WoT as well.
Add some Dispel, Dissolve, Acid Ball, Etherian Lifetree and Rajan's Fury and you may have the core of a spellbook.
This also seems to be a spellbook that could go very low on enchantments, the cats are certainly best used without any additional costs on them, so I would try to go for an enchantmentless book and add a Harshforge Monolith to punish the opposition.
PS come to think of it : a few copies of [mwcard=MW1C33] Sosruko, Ferret Companion[/mwcard] may fit in this strategy as well.
