hey cute kittens!
We have a few cats here and those pics made me remember when mine were that tiny and silly.

One thing I had to mention though. Ive had cats all my life,fostered cats,mothered orphaned kittens etc. My sister is a vet technician. Im telling you that part so youll listen closer to the next part:
I dont want to be a downer or an alarmist but if your kitten meows when it uses the litter box, while it may be entertaining , it could also be a sign of a urinary tract infection, crystals or other complications that could potentially be VERY serious and even life threatening to such a small guy. No shit. I have seen it many many times. Most problems are easily fixed if treated in time.
It may very well be just a peculiar bahavior and nothing medical but the implications of ignoring a possible medical explaination are too great. I would suggest a visit to your vet to make sure. Call first snce they will have pre-visit instructions for you.
Call them....TODAY....NOW. Im not kidding. You wouldnt waste any time if you were pissing fire. Even if your vet rules out UTI etc you will be better off safe than sorry, especially if both cats end up with it.
I hope they are fine and that he just likes to sing while he pisses!

Oh, btw its not an expensive visit or test. Even though you should always be prepared and capable of paying for their medical care if you take in an animal , if cost is an issue all reputable and ethical vets will discount their services if you express financial diffculty.
