I like cats because they are less maintenance. Also, when they come to you it's because they love you. Dogs come to you because they want food or something.
I have both, but I prefer cats. My cat henry is declawed and is the most docile creature on this earth. You can hang him upside down play around with him and he is a spaghetti / lasagna fan. I had left dinner up on the stove over night, it had to be at least a 1/2 full pan of sauce, and it was gone by morning, mushrooms, meatballs and all...
Both eat. Both shit. Both will come back if they know where the food is coming from. I've got both, and rather I did not. All they do is cost me money. Like I said, they both shit, and both eat... That's about all they do.
i agree with melbel. i love cats because of their low maintenance and they're more adorable. they're cute.
