This week, a couple in Pennsylvania trapped a strange rodent: a purple squirrel.  They were trying to deter the neighborhood squirrels from raiding their bird feeders by trapping and relocating them (not the best idea - see below for more info on why). 

No one believed that they had a purple squirrel living in their yard until they trapped it and took these photos, which I grabbed from the Facebook fan page that has sprung up, and were taken by Percy and Connie Emert.

No one knows why the squirrel is purple, but there are many theories.

Trapping and relocted wildlife isn't the best idea.  It's often illegal to transport and release wildlife.  Often the animals that are released far from their home territory are put at risk from the resident animals of their species, which will try to drive them out or even attack them if they're a territorial species.  Even if they're not, an animal dumped in unfamiliar habitat might not be able to find food, water and shelter.  You might also be moving an animal that has babies (squirrels start giving birth as early as February in some areas).

Here are some better ideas on deterring squirrels from your bird feeders.  Find out how to create a wildlife-friendly yard from the National Wildlife Federation.

This odd behavior isn't really so odd if you know a little bit about cats' natural bathroom proclivities.  Generally speaking, unless they're scent marking for territorial purposes, cats naturally cover their waste.  This is true of wild cats as well as domestic ones.

This is why a litter box works.   Cats naturally find one spot to go to relieve themselves, and they prefer to pick a spot with loose soil or leaves so that it's easy to cover up their waste.  Given the choice of a doing their business on a hard floor or a carpet versus a box filled with kitty litter, most cats will natually pick the litter box.

In this case, when the cat turns around and paws at the back of the toilet, she's not actually trying to pull the flush handle even though that's what it looks like she's doing.  Instead, she is just doing what all cats are hardwired to do: cover their waste.  The fact that there's no loose soil or kitty litter to do the job doesn't matter when it comes to this powerful instinct.  The cat has to go through the motions nonetheless.

So while it looks odd and is definitely chuckle-inducing, it's really just a cat doing its natural thing.

As a one-time owner of a rabbit, I can say that this video doesn't surprise me at all.  My bunny was actualy rather intelligent and interactive.  He loved to play fetch with a rolled-up ball of newspaper.  He'd often run in circles around me as I sat on the floor, holding the ball in his mouth.  When he lost interest in fetching, he'd happily unwad the newspaper ball and shred it.

My rabbit was also very interactive with my dogs and cat.  Being a "house rabbit" he had free run of certain (bunny-proofed) rooms and developed quite a bond with one of my dogs.  (Although I think the reason my dog loved the rabbit so much is that he recognized that the bunny was the source of an endless supply of "raisinettes" out of his backside.  I know it sounds gross but rabbits eat their own poop in order to digest their food twice and get the maxium amount of nutrients, so it couldn't be too bad for my dog to get an occassional treat fresh from the bunny's behind.)

Here's a great video about keeping rabbits as pets.

While backstage, I bumped into some of my friends from Animal Planet, including Dan Schachner, the new Ref for Puppy Bowl, the annual event that's the perfect thing for all of you non-sports lovers out there.  Dan had just finished doing a segment of his own with some super-cute puppies.

Puppy Bowl is an oddly genius idea that started back in 2005 as a fun alternative to the Super Bowl.  Essentially, it's several hours of puppies romping and playing on their own football "field."  Never underestimate the power of cute puppies, because as silly as it sounds, Puppy Bowl is a big viewer favorite every year! 

This year there are even more animals involved, including Meep the Bird who will tweet all the action from inside the stadium and a piggy pep squad that will "ham" it up on the sidelines and squeal with delight for their favorite pups.  Yes, I said piggy pep squad.

In other words, Sunday can't get here soon enough!

What's odd about it to me is the synchronicity that the otters show as they cavort in pursuit of the fleeting insect.  Otters live in family groups but such groups aren't like a flock of birds or school of fish that move in unison almost as one living thing.

Yet in this video, they might as well be! Like I said, awesome.

Nothing is cuter than an otter!
