Is TS4 Cats & Dogs worth it?

Haven't bought it yet as am still researching. Am likewise finding throughout the forums an enormous number of complaints/bug reports, lists of things former pets versions had but this does not, and general not living up to expectations. Yes, a lot of folks are deliriously happy, much of which seems to come from the cuteness factor. Will admit to being attracted to the new town and a fair bit of the build/buy, but am not parting with $40 to get just that. If I get it, it will be on a deeply cut sale.
