"They like to bite off more than they can chew so of course they have to spit it all over the table"

I understand, and agree, that the root of the problem is the amount of abandoned animals but I still think that what peta does is wrong. By accepting more animals than they can care for they are robbing those animals the chance to find a shelter that can actually take them in, or someone willing to adopt them, or a temporary foster home, even a life as a stray could be better than death IMO. Euthanasia should only be used as a last resort, I dont think peta is doing enough to exhaust their options and, I reiterate, they are not allowing others to try by pretending to shelter those animals. A no rejection shelter that kills the animals they cant care for is just a regular shelter with extra (and careless) steps.

If you are pro-pets and do not fund PETA to support all the neglected pets it feels a bit hypocritical to criticize them for euthanizing

I can barely fund myself

If you are pro-pets, don't buy "designer" puppies. Get your animals from a shelter, or from rescues.

I absolutely adore betta fish, but I sure as hell won't buy one. I don't want to support keeping fish in tiny cups.

Frankly, what we need is legislation that forces pet stores to ensure that any animal kept with an intent to sell mush be housed and displayed in an appropriate enclosure for it to survive its entire natural life. That way the animals don't suffer if they aren't sold, and people get a good idea of what an actual appropriate setup looks like for that animal. I see too many nightmares on Craigslist and Facebook where people are keeping a 5ft corn snake in a 10 gallon enclosure because that's what the baby corn snake was in at the pet store.
