I hear you. I agree that not everyone takes the most ultimate care of their animals, but for the most part, I take my hat off to most individuals who have animals whether it's farm animals or house pets.
Most individuals with farm animals are in the business of exploiting them for meat or, milk, eggs or wool and then meat after the animals' productivity drops off. So when you say you take your hat off to most individuals who have farm animals, are you including people who are farming them for profit or are you talking about people who keep farm animals as pets? If you are talking about people who farm animals for profit, then why did you even come to this website, to spread your carnist views? I don't take my hat off to them because I believe in animal rights and farming animals for meat and other products is not compatible with animal rights.
Keep in mind that when an animal ages, as humans do, their teeth and health declines. Our teeth get worse too as we age, and it's not because we didn't brush our teeth everyday. Unfortunately cats/dogs have a shorter life span than we do and you'll see their teeth decline sooner than ours.
Teeth should not be allowed to decline. In a human, if a tooth is not viable, it comes out, hopefully. The person is not just left to live with a cavity getting progressively worse and worse, while people say "oh well, teeth decline with age".
A feline cavity is called a FORL and it cannot be filled like a human cavity because it is actually a situation where the gum starts growing up around the tooth, which results from plaque growth, and it creates a very painful situation for the cat and the bacteria from it gets into the bloodstream and causes problems for other organs, such as the kidneys. So if a cat has a FORL on a tooth, the tooth needs to come out, and if every tooth in the jaw of the cat needs to come out due to FORLs, so be it. Cats don't need teeth to eat wet cat food and they can even eat dry food without teeth but they shouldn't eat much dry food anyway because it's not as healthy as wet food for cats.
If you don't want for a cat to get FORLs, daily brushing is essential to prevent plaque buildup. But even when you do brush every day, sometimes they get FORLs anyway, but not as many.
I have 2 cats and clean their teeth every so often and have had them cleaned, however, I do not clean them everyday and probably will not incorporate that into my daily routine any time soon. I can also say that my cats live quite a happy life and have it pretty darn good. I've had horses and hens also. They also were well cared for. None of my animals were "mistreated" as you refer. However, if you're going to use the label "mistreated" because one doesn't clean their cats teeth everyday, then I guess you will say I mistreated my spoiled cats. I had horses and hens - I wonder how you're going to say I mistreated them? I'm curious to know.
Maybe "mistreat" is too strong a word to use in a case where someone doesn't take care of a cat's teeth but it is definitely inadequate care to not take care of a cat's teeth, and since maybe 99% of people do not care for their cats teeth at all, that same percentage of cats receive inadequate care from their owners in my opinion.
But I think the word "mistreat" fits perfectly to a situation where someone pays to have a chicken or other farm animal tortured and then slaughtered just so they can enjoy the taste of flesh or milk or eggs. And if you buy and eat animal products, that is what you are doing and that is a more pressing issue than how you care for your cats, and much more important than how you have cared for animals in the past that are not even in your possession any longer.
I only responded to your post because I was attempting to instill some positive outlooks on the negativity that I saw in your post, because there are wonderful people out there taking great care of their animals. Sometimes negativity and only seeing the bad out there leads to more of a glim outlook which can ultimately cause a decline in overall happiness and content. I hate to see that self destruction in an otherwise good person.
You were trying to spread your carnist worldview that says everything is just peach keen, most animals in the care of humans aren't mistreated, they are just slaughtered when they are very young but that's fine because animal exploitation is okay. To me that isn't positivity. It is just someone who does not believe in animal rights talking about how great animal exploitation is.
