Gato

I have be thinking about getting one or two cats. There is a cat I really like in the humane society called Celo (which is the word for blond in Mayan).
He is very cute. He's about 1 1/2 years old and plays gently with his claws in. There are pro's and cons:
I would love the company and a cuddle from time to time, he will rid my apartment of roaches; this cat seems very easy going and I bet I could put a harness on him to take him outside. The downsides are that I would have to arrange boarding for him if I go on vacation. He would have to have a litter tray in the house which would take some cleaning; my landlord is OK with me having a cat but the lady who looks after the grounds here, Nellie, has some bad experiences of cats pooing in her garden - so I'd have to make sure that did not happen. He'd get lonely which begs the question would two be better? Philipe, my landlord, thinks one at first so as not to upset Nellie.
Its funny, I think getting cats or a dog is almost like having a baby in a 'scaled down' way. When I got Bigsy and Betts I was with Geoff and so we shared the responsibility. This would be me all on my own. Is getting a pet more of a couple thing to do?? I may leave it a little while. Perhaps see how much time I have when I get a job.
