A Extra Affectionate Kitten or separation anxiety

Tuesday my boyfriend and I went to the local humane society to look at the new facility and ended up falling in love and bringing home a 5 month old fix male kitten. At the humane society, we spent probably a good hour in the "kitty-city" where they kept several kittens of the same age group. He was very affectionate in the shelter setting, even with all the other kittens there. All he wanted to do was lay on my lap, he would occasionally go elsewhere, mainly because I think he was getting tired of competeing for lap space with the other 6 kittens wanting on our laps. Anyways, Tuesdays and Wednesdays are our days off for both my boyfriend and I. During those two days, the kitten, which we named Chacho, was just as affectionate as he was at the shelter, however, now with an entire 2 bedroom apartment to roam, he now follows my boyfriend and I around constantly. He was a vocal kitten at the shelter but now if he feels like he's being ignored, he complains. When I'm fixing food in the kitchen, he's at my feet meowing. When he's trying to get comfortable on my lap, he coos and mews. When I'm sleeping in bed, he trys to bury his head in places like my neck, elbow, and armpit. Today during a pre-work nap, I woke up to him attempting to nurse on my ear. He does go off on his own, but for very short periods of time and usually to see what the other person is doing or to eat or use the litterbox. Both my boyfriend and I work late shifts. He works until 12:30am, sometimes later and I work a night shift from 11pm to 7 am. Tonight is the first time that Chacho will be on his own for any length of time.

I know I'm jumping the gun, and that there may not be any problems but I'm just curious what other people with cat experience thinks of the current situation. Do you think that Chacho is just a very affectionate kitten or if it could be separation anxiety? I know until we find out how he reacts to our homecoming and its hard to tell especially when since we first saw him in the shelter, he's been nothing but affectionate, snuggly and vocal. Would appreciate feedback and opinions. I've dealt with cats that has had separation anxiety and know how to at least help lessen the anxiety but its a little harder to pinpoint separation anxiety in a new kitten.

Thanks for the response. I was worrying for no reason, I got home and the only thing awry was the kitchen trashcan was knocked over and it didn't even look like he got into the trash. By the way the trash bag looked, he thought the excess bag sticking out from under the lid was a fun toy. Yesterday he seemed to be a little more independent...only just a little.

If it wasn't for the pet deposit $200 for one pet, goes to 3 for 2 pets and then the additional charge added on to the rent each month per pet, we probably would've came home with his brother too. They were doing a special on him and his brother, you buy one, get the other free but the price jump from one to two pets is a little more than what we can afford. Plus I don't mind having a cat that follows me around like a dog and wants affection constantly. I was just worried that he would be too attached and would go crazy when left alone but I was just being paranoid.

I had to be away from the apartment for a few hours after my boyfriend went to work today. I had left the T.V. on for white noise and when I got back home he was sitting on the couch staring at the t.v. So he's been a good boy and he's starting to recognize when we're scolding him for being on something he's not suppose to so that's great too. He's realizing that if he wants to be at "our level" when we're sitting that the table eating, that he needs to sit on his little cat tree, not the table, which is great. That's been the hardest thing to deal with, but he's slowly getting the hang of it.

I could ramble on and on about my little guy, so I'll stop XD

Callista & Rosie: I usually make sure that I can fit a few fingers under his collar. I did have it pretty loose that first day because in my experience with cats and collars, they seem to get use to the collar a little quicker if you let it be pretty loose the first time you put it on them. I supervised him the first day really there wasn't much supervising because he was sleeping on me 99% of the time. I think, to a cat who's never wore a collar, it must feel like they're being strangled (even it they're not.) I have a similar feeling each time I wear a turtle neck XD Anyways, I've tightened the collar up a little bit, its still relatively loose but not to the point I have to worry about him getting stuck in his mouth or getting it stuck under his arm. In some pictures it still looks pretty loose but that's mainly because he as a very long neck and it just sits lower down so it looks like its hanging a lot.

Blanche: Oh yes, he's def. a teenager and loves to test boundaries. He usually blantantly ignores boundaries if milk is envolved. I pretty much have to stand when I drink milk or eat ceral. If I sit, he's all over me. Yesterday, he was trying to squeeze his head through the gap between my index and middle finger of the hand I was using to block him to get to my bowl. Then he got super fustrated because he couldn't fit so he just had his nose pushing through the gap, complaining the whole time.
