WTF? Your cat is looking ripped and swole!
I hardly think she needs any nutritional advice at this point, besides, you wouldn't want her to be non-functional when a mouse or rat showed up, would you?
I recommend putting in some submaximal dead mouse lifts for that long back... just by way of some sport specific training.
Possibly some plyo's for the max leap, I'm sure the top of the fridge won't be off limits for long!
Hey, not everyone has the same goals as us y'know.
For adequate recovery, perhaps you could add contrast sleeping pads, one hot and one cold?
