Stop the Overpopulation of Pets

I really have no idea what to say. Reviews elsewhere warn people of the cats here, mainly their poor health and poor conditions they live in. I went all over the city and the surrounding areas looking for the perfect companion for our one year old maine coon kitten.
The drive took us an hour but it was worth it to meet little Lilly, her name before I will not say. This rescue is in a home and there are 2 bedrooms off the living area full of cats. One room was for sick cats and the other for non sick cats. We were greeted rather coldly and soon realized the lady here, who I assume runs the place, is a very sarcastic woman who loves to remind people of how much she hates her job and never gets a day off. There was my first sign. I told her who I was and who I was there to see & eventually (nothing here is done quickly) she brought the kitten to me, who (size wise) I thought was 2 months old. She was just as adorable as her picture and my husband had his mind set almost immediately. The ladies here didnt ask if we had questions, they didn’t offer information on this kitten, they didnt even tell us if she had her shots or if anything was ever wrong with her. 15 mins later, still being ignored we left.
We came back a week later to ask questions. Turns out she was hit by a car, had her jaw & arm broken, and was actually 5 months old. Mind you this kitten was a under 4lbs and beyond frail. I thought for sure she was a new kitten to this rescue and hadn’t had time to fatten up yet. Nope. I informed the lady there, Diane, that I had a vet appointment the following week for her already scheduled and that she would receive whatever care was needed to get her better. She was shocked. She told me, rather bluntly that the kitten was fine, had all her shots, and was negative for everything and then showed us her medical history. Keeping true to myself, I kept the appointment just in case it was needed. I’ve fostered in the past and I know just how sick kittens can be, even if properly cared for.
One week passed and it was time for her to see the vet. I brought her in and gave them a list of symptoms for this kitten who I was told was not sick. The list: ear mites (her ears were BLACK!), tons of scratching (ears and whole body), way too thin esp for her age, dull eyes, swollen gums, poor appetite, bloody & green stool mixed with diarrhea, sneezing, and she wouldnt play and seemed rather terrified even after a week in my care. She wouldnt even eat if I was watching her. She wouldn’t play, like I said, but this kitten was not use to human contact which was very strange since she had over a month with this lady at the shelter. There was no reason she wouldnt have been given proper attention and socialization. Right?
The vet’s verdic? She had a major ear mite problem and a severe ear infection that was never treated which caused her poor little ears to be filled with so many dead mite bodies that she was suffering with a horrible inner & outer ear infection. Ear drops for 2 weeks. She had a cold which would explain the sneezing. She has a very bad gum disease that was also never treated so her poor little gums were so swollen that she was not able to eat without pain, so she wasnt eating. This will be a problem forever now and she’ll need cleanings for the rest of her life. Her poop was green and bloody due to a parasite known as Gilardia. Some people dont treat for this, but when it’s in a severe stage it drains the life from animals, including humans and can cause death. Any food she was managing to eat was stolen from her for the fact that this parasite doesnt allow any nutrients to get to the animal. It latches itself to the intestinal walls, thus the blood in her stool, and reproduces itself causing a HUGE problem for me and my other pets. It’s a VERY infectious illness that only gets better with some serious medication, so poor Lilly is stuck in a cage.
Lately Lilly has been getting better slowly. The medicines she’s on have given her eyes some color back and she’s playful now. She even has interest in my older cat which is huge since she was also so terrified. Her little ears have been cleaned thoroughly and the drops seem to be helping the pain for her. This will be a long process and would have been very preventable if anyone cared to notice them, let alone made sure she was getting proper nutrition from the start. With such a poor diet she had no chance fighting off the diseases the other cats from here had. She came from the non sick room mind you.
If you do not have the patience or money to fix a cat with (possibly) several problems you should look elsewhere. She does have a lot of cats who are very friendly but it’s obvious she does not care for them like she claims. Half of these cats were clearly sick; sneezing, puffy oozing eyes, green diarrhea, etc. The other half dont look sick, but clearly are. Diane could be nicer too. Maybe she could start with that.
