Female cats don't spray. The Males do. I grew up with cats. One time we had 13 of them. lol That is a lot of tails in the kitchen at feeding time. :-D We have three now. I love cats. Keep the litter clean twice a day, and you can get the arm and hammer litter deoderizer that is in the litter section at your store. That works wonders. We feed our cats Fancy Feast can food. We divide one can in 1/3 for each cat. Then we use Purina cat food for Sensitive Systems (dry food), and leave a small bowl for them to munch on throughout the day. At the pet store they have books on cats as well. Since you live in IL, you must get snow. Cats love the outdoors, but God didn't give them the sense enough to be out of harms way like with cars etc. We keep our cats strictly indoors. They love it. And they're safe. :-D They don't like change too much. If you have a tree house for your cat, put it near a window or sliding door so they can lay on it and look outside. That's cat tv for them. They love it.
There are regular shots that they need each year. If you can't afford the vet bill, at least get your cat her rabbies shot when it's due. Oh, and the Feline Leukemia shot as well. It is expensive each year so try to save up for it. Cats are also very tolerant of pain, which means they will not show you that they are in pain. So keep a close eye on your kitty to make sure she doesn't show any signs of different behavior. If you go to pet your cat and she is in pain where you pet her, she will nip at you. That is a huge sign that she is hurt. When my Ginger kitty had a urinary track infection, she bolted out of the litter box, ran straight for my bathroom and hid in the shower. There was blood spots everywhere. I panicked! I was so scared for her. She was panting too. Another sign of them being in pain. I called my husband to come home right away, and we took her to the vet. She got on antibiotics and got all better. We've had our cats now for 8 years. I hope all this helps you. Please feel free to email me if you have any specific questions that you have. Enjoy your kitty! :-)
