I don’t know how to stop my cat? Help?

Wow. This is a challenge. Not sure what to really suggest. Have you tried putting the Feliway plug-ins around in the house? Also may want to look into some kind of enclosure where she can go outside but be safe - enclosure attached to the house via window or door.

She sounds like she has too much built up energy. Caging her at night is making things a lot worse but I can see why you do it with her eating and destroying things. Any chance of just confining her to to a room with minimal furniture? Also you need to see another vet. You may need to put her on prozac for awhile. If she is eating non-food things (and things that can potentially harm her), she has what is called "pica" and you need to find out what she is lacking in her diet.

I would also make sure she has nails trimmed weekly and use the SoftPaws nail caps on her too.

Just so everyone knows, I have plenty of experience. I’m not working currently because I am going through veterinary studies. Doing catch up courses online before my official course next year. Zannah is doing much better now, with more research I was able to get the best vet possible and medication for her. She still has some issues but those are just more behaviour things that can be treated over time.

Then give her up to a no-kill shelter. Why do you have pets when you don't even have a job?

This does not sound like a good match for you, regardless. I would rehome the cat.

I know no vets who are behaviour trained, they can sell you chemicals they earn commission on based on what the sales rep told them, they can sedate the cat nor are they qualified in cat nutrion again they rely on afvice from the food sales reps and commission on what they sell ..vets are trained/qualified for health/medication ONLY .... so if you need behaviour advice then book and see someone who is trained/qualified who knows what they are talking about.

Based on what you have said the vet is talking trash.feral cats do not nap on your knee and change personality, even ferals who have been caught at an early age and 'tamed' tend to make good pets BUT they are always aloof.

Are you making this cat an 'indoor cat' as it sounds bored it also sound like it is over stimulated in the wrong way which is leading to frustration , could be increased by what you are feeding, if so you need an cat pen outside where it can go in the day/some of the day, it needs more activity as in a cat tree, scratching post and less over simulation by you ( as in playing 24/7 etc etc)

My advice ( trained/qualified advice) would be to get in touch with a TTouch Practioner ( or PiT) who can assess the cat, do some work on it and give you some 'off handling' advice like using a 'ttouch wand' so you are not being attacked nor is the carpets/furniture

First, check the cats diet? Diet can impact behavior.

Have you talked to your vet specifically about her behavior issues? You may need to consult him to see what he thinks.

Don't rush to rehome. I hate people who suggest that. I know you want to figure out a way to fix things and you SHOULD want to do that first.

Does the cat have toys? Trying playing with your cat to tire her out. Change her diet to better quality foods, if she isn't eating them already, find things to occupy her when she acts up.

Cats are not dogs. They do not belong in cages unless being transported.

This cat clearly has pica. If none of your vets have told you that, you need a better vet. If your 'animal behavior training' hasn't covered medical conditions that effect behavior, you need better training.

Get her claws trimmed and have claw caps put on. Your vet can help you with this so she isn't super stressed for too long.

It sounds like she is super stressed, not 'just a feral cat'. If she was a feral cat she wouldn't allow you to touch her, even on the good days.

It sounds like you need to play with her more, and create a more stable environment. It sounds like you have more than one cat, that can be an issue. How did the introduction process go?

Do you have the cats on a feeding schedule? If not, you should. This helps create a more stable routine.

Has she been fully checked for internal parasites? Worms and other parasites can cause serious digestive issues, so she may feel hungry when she isn't because she isn't getting the nutrients she needs, causing this chewing problem. If she hasn't been had a full fecal test done, she needs it.

If she is not on a proper flea and tick preventative, she needs to be. Fleas can cause tons of behavioral issues, and tons of health issues. All of the animals in the house need to be on a flea and tick preventative.

You also need to play with her properly. Get a feather on a string type of toy. Never use your hands. have scheduled play time in the morning and evening.

Listening to you rant about one single cat says that you are very inexperienced and probably did not take the cat to any vet who would have prescribed tranquilizers. For those reasons, I believe you are a troll.

If you really do have the described cat, get ahold of me and I'll take her and tame her as I've done with LOTS of feral cats!

Oh for god's sake, it will not get any better, take the cat to a shelter, do not impose it on anyone else, the cat has serious problems.It may be that the cat has to be put down.

I hate to suggest this, but if it's a matter of maybe saving her life, think about getting her declawed. Once she doesn't have them anymore she might calm down a little. Like I said, this is only as a LAST resort.
