What you feel like is irrelevant, the animals needs come first.
This, right here.
I love my cats, I love my fish, I've even become attached to the daddy long legs in my laundry, I understand an attachment to animals...
Granted we all get lazy. Granted we all postpone a change for a day here and there.. But this is ridiculous. Honestly it's kind of starting to seem like you see an animal then all of a sudden it becomes your "neglected pet" and suffers for the rest of its life.
If you love them as much as you say you do you wouldn't make these excuses. You'd do the maintaince regards of if you can be "bothered". I'm still over 15kgs underweight, I know what a lack of energy is yet I still care for all my animals.
If my animals ever hurt themselves and I didn't have money for their treatment, I'd sell something. I've done it before and I'd do it again. When Rumpy ate an ivy plant I didn't have lots of money, so I sold my TV, ds, and home theater system so I could pay his vet bill. Why? Because HIS NEEDS and HIS WANTS come before mine. Your a kid, surely you have a PlayStation lying around somewhere that you don't use. Or games you don't play, or whatever. If you're allowed to, sell some junk (yard sale!
) and get a new pump for your koi.
Getting pets is similar to having kids (except I can leave my 5yr old cat at home by himself all day and he won't be dead when I get home), when you commit your life to looking after another that becomes your main drive in life whether its a child or a pet, what YOU want doesn't matter anymore because you've committed your life to bettering their life.
Why have animals if you're not going to look after them? I know maintenance and cleaning after pets isn't fun, I mean, do you really think I enjoy cleaning 5 kitty boxes every day or two? No, I don't, it smells, its gross and then theirs Rumpy's "issues" and omg! But it has to be done. That's what I committed to when I got cats.
Do you think I like rinsing out floss covered in fish poop? Do you think anyone likes doing that stuff? No, but they do it because that's the commitment they made when they started keeping fish.
Carp, I like you, you seem like a good kid. However I think its time you started really thinking about whether or not you're giving these animals the best life you possibly can or if you could do better.
If you can do better its time to think about do you want to, and how.
If you don't want to do better or can't be bothered, please re-home your animals, for their sake. If you're willing to let them suffer, you don't love them as much as you say you do.
I'm not trying to be mean here but someone has to say it. I'm not trying to offend or upset and I don't want to argue, just voicing opinions.
Post Script: Sorry for the wall of text.. Animal neglect bugs me.
