I'll be honest, I'm a dog person but my mum and dad have 4 cats, 3 of which came from me, all abandoned! One had been threw out the window of a car in a bag as a kitten, I found it and my parents took it in (my fav and 15 now) another just a stray kitten that turned up and my house and the latest was tha same story but he survived nearly being killed by my dog and then a 40 mile trip under my van in the spare wheel (which is stored upside down) under the van, couldn't believe it when I seen it beside me on a site 40 odd miles from my home!! (Prob only about 10-12 weeks old at the time) So of course my mum took it too, first and last are tabby and have to say as cats go my favs, funny thing is that both them come and seek me out when I call at their house to spread out on my legs, the first cat does this with my parents too but the last little cat only does it with me although I rarely ever see him! My parents are convinced they know I 'saved them'
Have to say they are not a lot of hassle, need fed and watered and are easy kept, parents have an auto cat flat they all use and won't let other strays in, think it's a chip implant in the cat
As you say a dog is more demanding but I love the bond and physical interaction I have with my dogs, also the way I which they show you how much you mean to them, esp bullbreed dogs (very bad press but the most loving breed you could ever meet when brought up in a loving environment) and not by the the usual hoodied shite bag you see then with that just bought it to look hard.
Just one thing, vets bills can be expensive if you have a sickly one! Two of my mums are always in and out of the vets with various issues, saying that my last dog cost me thousands but I didn't care, I'd have sold everything to get the money to treat him if I'd needed to.
But yea, cats are pretty cool tbh
Word of warning, they can be a bit destructive with any fabric furniture, they claw at it to exercise and sharpen their nails (which you'll prob find out at some stage are like razors!) Lol
