I just came out of the shower to find the cat on the stove, chewing the bread out of the plastic sleeve. She somehow hit one of the knobs and the kitchen reeked of gas. This is about more than annoyance now. This cat is so poorly behaved that she's an actual fire hazard.
Thank you to everyone who replied. Calling the shelter tomorrow.
Do it. It sounds like she needs a different kind of home and she is kind of feral and difficult. We had to do this too, with a kitten who just wreaked havoc in our home and with our existing cat who is now very well behaved since the kitten has been rehired.
Fxxk those who have judged you, and just do the best you can. Good luck.
