Weddingbee boards

Okay, he's not so much a kitten anymore, but he's my baby, he's about 19 months, and he's really been the picture of health since we nursed him right after we adopted him.  (He had all kinds of problems at that point, poor little muffin.)  Anyway.  Sometime last week, I think Thursday, I noticed that he wasn't putting weight on his back right leg.  As in, he would try to put weight on it, it would shake a bit, he would decide against it and just sit down.  A few minutes later, he would get up and walk and run normally.  He would stand up on his hind legs, put his paws on my leg, beg for attention, as usual...he seems just fine.  But then a little while later, I'll notice the no weight on the back leg thing again.  I was out of town this weekend, but I gather from FI that he didn't notice anything more until Sunday, when he started doing it again.  We have poken and prodded the foot and leg to see if anything is stuck in it or if he seems to be in any kind of discomfort.  We haven't found any foreign objects, and while we sit and push on the leg and foot, bend it around, twist it and turn it...he purrs.  A lot.  So.  Should I just let it go for a little while and see what happens?  It doesn't seem like an emergency situation, right?  I don't need to be rushing him to the vet?  I assume that if I do, the vet will want to do an xray--anyone have an idea of how much that will cost?  With the wedding coming up in less than 3 months, I have NO extra cash, and I just want to have an idea of how much I'm not going to be eating, because obviously, I will spend whatever I have to to make sure he's okay. 

My instinct is to wait a bit and see how he does.  I tend to be a panicker, and I'm trying to work on that.  So, help me, bees!  Anyone dealt with anything like this before?  What did you do?  And here is a picture of my little one so you can see how he has captured my heart and caused me to obsess over his every need. 

Ok, you ladies have already made me feel so much better! Thank you so much!  I'm glad y'all think he's cute--he's pretty much my favorite thing in the world.  :)

@Quietserenity - I didn't even THINK of that!  I will check that next time he does this!  Thank you!

Your kitty is so cute! I love orange tabbies, I grew up with a cat who looks just like him! They are the greatest :) I like the idea of calling the vet and seeing if they think it's something you should come in for.

@rosy - That's EXACTLY why I don't want to call the vet yet!  Thank you.  I just know that they'll tell me to come in--if I was a vet I would too.  I wouldn't want to say to someone, "Nope, I'm sure your beloved pet will be fine, don't worry about coming in" and then have it turn out that something was seriously wrong.  That would be a huge liability.  So of course, they would tell me to bring him in.  So I guess I give it a little while and see how he does?  It doesn't seem like anything is broken--if it was I doubt he'd put weight on it or purr when we messed with it.  But it still seems fishy.  *sigh*  My FI says that it's a ploy for my sympathies--if it is, it's working because every time he does it, I fawn all over him and he gets lots and LOTS of attention.  Wily cat.
