I can't argue with true members of PETA, the only words they'll take into consideration are PETA's own words, and it even seems they turn a blind eye to some of those.

I can take a look at PETA's letter, a look a the opposition's claim, and understand the truth is probably somewhere in the middle. Looking at the reports, it appears the bulk of the numbers are cats (well over 1000 cats euthanized per year). Based on PETA's claim that they euthanize ferals (rather than TNR), I'm guessing a great many of the thousands are feral cats.

"Unadoptable" is all a matter of perception. I'm sure by their standard, Tommy would have been unadoptable if he had arrived at their facility. He most definitely would have cowered in the back corner and peed on himself every time a human approached. But put him in a house and with a bit of love and patience he became a wonderful companion.

The sheer number of
dogs without homes is far too great to even attempt rehabitation
I disagree. There are sanctuaries, foster homes, rescues, etc., devoted to that very thing. PETA could afford to do more in that area, but they prefer to put their money into their anti-meat campaigns.

That letter plays on emotions and mental images without really explaining much in my opinion. For all I know, they are claiming a dog with a runny nose is "extremely sick and better to put it down than subject it to further trauma." Or it may not be that way at all. The thing is, that is put out by PETA so of course they are going to put the best light possible on it. Blindly believing everything they say word for word would be no better than blindly believing what CFF says word for word. People were skeptical about the numbers at all, but I guess we can all realize that whatever the circumstances, the numbers were true.

edited to say:
Liz, I agree about the hand/food test. That is very sad. Because a dog may nip at some strange plastic hand coming into its bowl should not decide whether it lives or dies
