Wandalust, my cats are 2 yrs old. They were born to a feral mom. I have had them since 7 weeks. They eat Avoderm premium food plus Wellness dry food, given in a ball that rolls so they have something to play with. They have towers and toys everywhere. They are orange brothers. Their favorite thing to do is wrestle with each other.
Their teeth and health are fine.
They mostly like to chew rubber bands, phone charging cords, strings hanging on anything, and headbands. Needless to say, they have made me have a neater house.
The last thing they chewed was the plastic drain pipe from my washing machine. Maybe they were bored, but we are home full time and can't entertain them 24/7. Now a Scat Mat sits on top of the washing machine. The new hose and service was $200.
I live on a farm. I have had lots and lots of cats. These are my first destructive ones. They are the only two in the house, no dogs. For me, thank heaven, I had them declawed early, or else they would have ended up in the barn. They have no idea they are declawed, and scratch on everything. I think they would have been happier as barn cars, where they could be outside chasing stuff, but now they never go out.
They also jump up on the kitchen counter all the time unless I have a scat mat on it. They have made me much neater. I thinks its the feral inheritance.
