If it's any consolation, they do tend to grow out of this stage. With my first cat, I was redecorating the tree every day when I got home from work. With two, we started to tie the tree to a plant hook in the ceiling to keep them from knocking it over.
I stopped buying any glass ornaments for a long time, because they managed to break about 4 boxes of them. I put the last 5 or 6 of those first red glass balls in a clear vase with a ribbon this year.
My MIL made me a beautiful felt appliqued and sequined tree skirt. We went out of town, leaving the cat in the care of somebody who came in to feed her. When we got home, the cat had methodically peed all around the tree skirt. There was no fixing it, though I tried.
Now, those cats are long gone and we have two more. We have two trees they mostly ignore, and I've even started buying glass ornaments again.
I made a jewelry box that I use when I travel out of a check box. I covered it with quilted fabric and then padded the bottom with fiberfill and covered that with more fabric. It holds everything I need for a trip and the padding keeps it from getting jumbled around. You could probably do the same with one of these boxes.
I used to joke that the only good thing that came from my first wedding was the 12 yards of tulle from my wedding veil. It's all gone now, but through the years I used parts of it for a tub toy holder for my son (the one from my 2nd wedding), a minnow catcher, a pool cleaner, a cover for lemons when we did a fancy Caesar salad at a party, a covering for the vacuum hose when somebody lost a contact.
I would bend a wire hanger and sew the tulle on it to create a net. The toy holder had a drawstring. Bunch some up for a scrubby for the sink.
I bought some beautiful Berroco Poppy yarn to make a pullover and then didn't get around to knitting it for a long time (25 years). By the time I finished the front, I realized there wouldn't be enough yarn to finish (must have shrunk , and there was no way to find any of the yarn anymore.
So, I made a purse. I lined it with a scarf, stabilized with unbleached muslin, and gathered the top and bottom on wooden handles and sewed up the sides.
It's dark hot pink, fuschia, and the tufts of color make it go with everything. I'm knitting a cabled scarf with the leftover yarn.
I found the pattern on a Jo-Ann's site. It's technically the same as most of the reversible purses I've made. The top is scooped, rather than straight across. Sorry the picture doesn't do it justice.
The outside fabric is from an old skirt that I was ready to donate, when I noticed that it was the same color as a linen suit (hanging behind the purse) I'm going to wear to a wedding. It's polyester, but feels like silk. I lined it with cotton in the same color as the flowers. Lining is hot pink, though it looks red in the picture.
I used Wonder Under with pieces from one of my husband's old oxford cloth shirts to thicken and stiffen the top fabric. I squared off the bottom and put a rectangle of flexible plastic between the fabrics to make it "sit" easily.
Cost: About $3 for the lining (I had a coupon). $2 for the beads.
