Well.. it appears that I have 2 sick cats. One appears to have a UTI so I have made an appointment to take him in to have that confirmed. The other has been throwing up. However, upon checking with My sister (who I got the second cat from) apparently this is a "norm" for him .. as he tends to have a nervous tummy of sorts. This might be true - but to be on the safe side I am going to take him in when I take My other cat in - and have him checked out just to be sure.
I will also say - neither of these "issues" stops either of them from being the crazy - running at full tilt - I want my snacks when I want them - cats that they are!
I love them to death - crazy critters!
