The brand new psuedo bulb that's coming up looks great, with no shrivels.

So, am I watering it too much? Is it not getting enough light? (Should I move it again)? Any suggestions?
Lastly, my cat somehow got into the bathroom (where I keep my orchids to insure high humidity) and ate the tips of a few leaves. The ones she ate off of have all turned yellow and died, but I assumed this was due to her munching on them. But now one of the non-munched on leaves is having the same problem, I worry that prehaps the dying of the other leaves may not have been due to her.
Any suggestions and/or advice?
Also, what kind of fertilizer would you recc. for this orchid?
Thank you so much!!

Hi Niki! Sorry to jump in late! A couple points though, that others haven't responded to:
<I noticed some black spots on the leaves and read that this indicates that the plant is receiving too much sunlight, so I moved it back from the windows (it still get light, it's just now not directly in the light) several weeks ago.>
The black spots are not a result of too much light but from spraying the leaves with water. The Oncidium Class orchids do not like spraying leaves with water of any sort. Just a heads-up. Move the plant back into the higher light. They really like high light (just short of full equator-class sunlight. Ful sun in latitudes north of 45 degrees is OK.
<I also noticed that the puedo blubs were shriveled, which I read means that it's not getting enough water. That website recc. that I allow the pot to sit in a litte bit of water. For the last two waterings, I watered the plant and let the base sit in about 1/4 inch water for two days and then drained the water away. >
As for this, Ray also responded. While you don't want Oncidiums sitting in water for more than 10 minutes max., you also don' want to let then dry down too much either. I find (for me) every 3-4 days watering is fine. Not all the psuedobulbs will be plump, ever. The only plump (smooth) psuedobulbs will be the latest ones to develope and then only while they are developing. The rest of the time they will have pleats up and down along the pseudobulbs. Some of the intergenerics will show a different pattern almost like shrivelling.
<Then, somepoint during all of this moving of the plant and watering changes, I noticed that the leaves on the smaller psuedo blubs have started turning yellow, which concerns me. (note that the leaves on the new psuedo blub look great, as do the leaves on the large psuedo blub)>
If the leaves you are referring to are toward the back of the plant (the part furthest back from the latest bulb) then all is well. Once an orchid starts growing new growths, it often starts dropping old back leaves because they are no longer needed for plant maintenance. A picture might help here with this point.
<Lastly, my cat somehow got into the bathroom (where I keep my orchids to insure high humidity) and ate the tips of a few leaves. The ones she ate off of have all turned yellow and died, but I assumed this was due to her munching on them.

Do you have any recipes for cooked cat?
Sorry couldn't resist. I don't ave cats because of the plants (I love cats and I love other people's cats even more!)
I just wanted to add that I think the perfect time to repot is now. 
Just my 
Hope that helps a little. 
but I agree with Sarah. Now is the perfect time. I just repotted three brand new Phals (2 in spike) from a reputable vendor and found to my dismay that they had merely put new bark on top to spiff them up some and that half the roots were rotted in the center of a pot filled with rotten sphag moss and some bark as old as Moses.
