I've always wanted to buy my cat a tower he can scratch, climb and hang out in, but never could bring myself to actually purchase those hideous carpeted structures. I mean, we have to live with these things in our homes too! I found these towers, however, at Post Modern Pets and I am smitten. I wouldn't mind having these colorful blocks in my apartment, cat or no cat (hey, maybe one block could even double as a side table).

The blocks are arrangeable and stackable in a variety of combinations, making it versatile for your space needs and interesting for your cat. An added bonus is that they nest inside one another for storage. Genius!

Here's another interesting item from Post Modern Pets - the hanging fish pod. Why not turn your goldfish into a piece of wall art? It might give your fish a different view of the world too (looks like this little swimmer has a nice window view). And if that goldfish ever passes on (and you know they all eventually do), it can double as a vase for flowers.
