In one sentence, describe what the following article is about: Make sure that the behavior your cat is expressing actually means that she's in heat and not sick. An unspayed cat in heat will vocalize a lot, be restless, rub against people and objects, and roll around on the floor. If you stroke her lower back, she'll respond by raising her pelvis and shifting her tail to one side. The normal breeding season for cats is between spring and late summer. She will likely go into heat during this time of year. Decide if your cat's in heat or sick. If she's acting restless, but not rubbing herself against everything and lifting her tail to the side, she may be in pain. Take her to the vet to find out what's going on. When she's in heat, your cat will grow even more excitable in the presence of males. Do not allow her outside at all, and close all windows and lock all doors, including pet flaps. To keep her calm (and prevent her from getting pregnant), you need to keep her away from all male cats. Isolation will also keep her safe she may try to escape your home if she senses a male outside. If you have a male cat in the same house, find a friend or hire a cat sitter to take him in for a couple weeks. If the two cats stay in the same area, they'll both act wild, and almost certainly end up mating. If male cats are visible through a window, cover the window with curtains or a piece of cardboard. Although success is not guaranteed, some people find that giving the cat a heat pack or a warm, wet towel to sit on keeps her still and calm. A microwavable heat pack may be the easiest option, since you can quickly reheat it once the cat starts acting up again. An electric heat pad/blanket is also a good choice. Cats respond very differently to catnip. Some relax and quiet down when given catnip, but other become energetic and aggressive. If you don't know how your cat responds to catnip, avoid this method. It may make the situation even worse. Note that this is only a temporary fix, but it might buy you an hour or two of peace. There are many herbal remedies on the market intended to calm cats. Some cat owners report success, but there is no single remedy that works on every cat. Furthermore, your cat may not respond to any of these products. Buy a collection of small samples and try several different remedies. Once you've found a product that works for your cat, buy it in larger amounts. Follow the instructions on the labels. They may tell you to add the remedy to the cat's water, rub a few drops into the cat's fur, or use as an air freshener. Do not use products intended for humans, which likely use higher dosages. Feliway is a synthetic cat pheromone that has a soothing, calming effect on cats. It takes a couple weeks of exposure to begin calming cats down, though, so it's not an immediate fix. If you know your cat is unspayed, you might consider plugging in the Feliway diffuser at the beginning of breeding season (spring). That way, whenever she goes into heat, the Feliway will already be built up in her system. Cats often scent mark with urine to attract males when they are in heat. By keeping her litter box clean at all times, you might encourage her to use it instead of scent marking your home. If she scent marks anyway, clean and de-odorize the area immediately. Leaving the smell of urine behind will only drive her to keep doing it. Don't use cleaning products with ammonia. Ammonia is also found naturally in urine, and the smell will encourage her to mark that spot again. Playing with your cat can distract her temporarily, but she'll often go straight back to howling after you're done. Petting, scratching, or brushing her lower back can be more effective, if your cat is already calm enough to let you do so.
Summary: Recognize that your cat is in heat. Isolate her from male cats. Give your cat something warm to sit on. Use catnip only if it calms your cat down. Test whether herbal remedies are effective. Use Feliway in your home. Keep her litter box clean. Play with your cat.

In one sentence, describe what the following article is about: Rhubarb is a cool-season plant that requires temperatures that drop below 40F (4C) in order to stimulate growth. The northern states in the US as well as Canada are good places to grow rhubarb. Check your growing zone to find out if you can grow rhubarb in the climate where you live. Rhubarb grows best in USDA hardiness zones 3-8. This includes much of the northern parts of the Midwest as well as the northeastern regions of the US. Rhubarb wilts during the heat of hot southern summers. If you live in a southern region where it regularly goes above 75F (24C), it will probably be difficult to grow this plant. Rhubarb is best grown from roots (crowns), not seed, since the seeds take a long time to get established and there's no guarantee they'll ever germinate. Go to your local nursery and buy rhubarb roots or purchase some from an online source. If you have a friend with a rhubarb plant, you may be able to dig up a crown from the side of their plant to get yours started. Rhubarb should be planted in an area in full sun. Look for a spot that drains well, since rhubarb won't do as well if water sits around its base. To determine whether soil drains well, dig a hole and fill it with water. If the water sits in the hole, the soil there doesn't drain well. If it immediately soaks into the ground, the soil is great for planting rhubarb. You may want to stick a ruler in the hole so that you can measure how quickly it drains. Ideally the water should drain out at a rate of 1-3 inches per hour. If it drains too fast, your plant will dry out; too slow and the roots may rot. Clear out weeds and other plants that may interfere with the rhubarb plants. Till your gardening bed to a depth of several feet and mix in plenty of compost, rotted manure or other organic matter to enrich the soil. This step is essential, since rhubarb needs plenty of nutrients to grow well. You can also consider building a raised bed to plant your rhubarb and other vegetables. This way you can control the soil drainage and weed population more easily. Don't treat the area with herbicides or pesticides; rhubarb should only be planted in clean soil. Don't use chemical fertilizer to treat the soil during the first year of growth; only organic material should be used until the second or third year. Rhubarb plants can grow to become quite large, so it's important to give them plenty of space. Dig the holes in rows. Place the roots in the holes and gently fill them in with compost-rich soil. Water the roots after planting.
Summary:
Determine whether you're in the right growing zone. Get rhubarb crowns to plant in the spring. Choose a planting site. Prepare the soil for planting. Dig 45 inch (10.212.7cm) holes 34 feet (0.91.2m) apart. Plant the roots 2 inches (5.1cm) below the surface of the ground.
