If you are looking for a plant that is easy to grow or you are the type of person who forgets to water their plants,then the owl's eye cactus, known as Mammillaria parkinsonii, is perfect for you. This is one of the Mammillaria species that is famous for its dichotomous branching, which is uncommon in cacti.  It gets its name from the unique appearance of its spines, which resemble the eyes of an owl.  

This unique Mammillaria has several other common names such as owl eye pincushion, owl eyes, owl's eye, cactus parkinsonii, or Nemammillaria parkinsonii.  Its unique feature is its alternating heads, starting with a single head and progressing to two heads, and so on. Because of its restricted growth and habitat loss, this mammillaria cactus is rare and endangered in its native area. 

Native to Mexico, the Mammillaria parkinsonii typically has multiple mounds that are blue green in hue, with clusters of tubercles that form distinct ridges along its sphericle or cylindrical stem. The spines are usually white or yellowish and are arranged in a radial pattern around the tubercles. What makes this cactus truly eye-catching are the central spines, which are longer and thicker, resembling the "eyes" of an owl. 

Mammillaria parkinsonii is a small to medium-sized cactus, with individual plants reaching heights of up to 6 inches and widths of about 4 inches. It is a slow-growing species that can take several years to reach its full size. The yellow, pink, and brown funnel-shaped flowers of this cactus are found at the tips of your cactus owl during summer. 

Watering Needs

When it comes to watering the Owl Eye Cactus - Mammillaria parkinsonii, it's important to be mindful of its specific needs. This cactus owl prefers a drier environment, so it's best to water it sparingly. Allow the soil to completely dry out between waterings to prevent overwatering and potential root rot. 

During the active growing season, which is typically spring and summer, you can water the Mammillaria cactus once every two to three weeks. However, always check the moisture level of the soil before watering to ensure it's truly dry. In the winter months, when your cactus goes into dormancy, reduce watering frequency even further to once a month or less. 

Remember, it's better to underwater than overwater this cactus. If in doubt, it's safer to wait a little longer before watering again. Providing proper drainage is also crucial, as excess water should be able to flow out of the pot to prevent waterlogged soil. 

Light Requirement

When it comes to light requirements, the Owl Eye Cactus loves bright, indirect sunlight. It thrives in a spot where it can receive plenty of bright light throughout the day, but it's important to avoid placing it in direct sunlight, especially during the hottest parts of the day. 

A south-facing or east-facing window is usually a great choice for this Mammillaria cactus, as it provides the right amount of light without exposing it to intense rays that could potentially burn the owl eye plant. If you don't have access to a suitable window, you can also use artificial grow lights to provide the necessary light for your cactus. 

Keep in mind that the amount of light needed may vary depending on your specific location and climate. Observing the owl's eye cactus for any signs of sunburn or etiolation (stretching towards light) can help you determine if it's receiving the right amount of light. Adjust the placement accordingly to ensure it's getting the optimal light conditions. 

In terms of propagation, Mammillaria parkinsonii can be propagated from offsets or by seed. It is a relatively easy cactus to care for, making it a popular choice among cactus enthusiasts. Additionally, this owl eye cactus is a friendly plant for both humans and pets. 

Optimal Soil & Fertilizer Needs 

When it comes to the optimal soil and fertilizer needs for the Owl Eye Cactus, it's important to provide well-drained soil that mimics its natural habitat. A mixture of cactus potting mix and perlite or coarse sand works well to ensure good drainage and prevent waterlogged soil. Instead, make or buy a well-draining potting mix, or ideally use our specialized cactus potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your cactus to thrive. 

For fertilizing, it's best to go easy on the owl-eye cactus. This mammillaria parkinsonii cactus doesn't require frequent fertilization and can actually thrive in nutrient-poor conditions. During the active growing season in spring, you can use a balanced cactus fertilizer once a year. Remember, it's always better to under-fertilize than over-fertilize this cactus. If you notice any signs of fertilizer burn, such as yellowing or wilting, reduce the frequency or strength of the fertilizer. 

Hardiness Zone & More 

The Mammillaria parkinsonii is native to arid and dry conditions and is generally hardy in USDA hardiness zones 9–11; which means it can tolerate temperatures as low as 20°F to 40°F. However, it's important to avoid extreme temperature fluctuations, as this can stress the mammillaria plant. 

As for humidity, the Owl Eye Cactus is adapted to low-humidity environments and can tolerate dry air. It doesn't require high levels of humidity and can thrive in average indoor humidity levels. Remember to always monitor the temperature and humidity conditions in your specific location to ensure the optimal growth and health of your Owl Eye Cactus.

Nope, not for Murphy the alligator hunter! 🐊🙄
Color: grass-green, Color: grass-green
Murphy, our 75 pound lab, loves to chew. We can’t give him anything soft or even anything remotely made for casual play as he chews them to pieces- literally. So when I saw this cute little alligator, with fairly good reviews, I bought it with high expectations. Nope. It didn’t have a chance- It’s in the garbage. ☹️ First I have to comment on the eyes. I don’t know what they are made of, but the “whites” of the eyes pealed off like paint within the first few minutes Murphy had it. He wasn’t even chewing at the eyes; they just pealed off. I can’t imagine that is good for dogs to ingest, but ok, I threw the white pieces away, and gave it back to him. I do have to say that he loved chewing on it- even without adding any kind of treat to it. So we watched him chew at it for about 30-40 minutes without it being dissected into a million different parts. I was impressed.... Until I took it away from him to be played with later.... during this time he was able to tear parts of the mouth (see pictures), and while all pieces are still in tact, I cannot imagine another 30 minutes of him having this in one piece. So, while I’m very aware that Murphy has limited toys to chew on, I will continue my search for indestructible toys for his chewing pleasure.

Cute toy maybe not for aggressive chewers
Color: grass-green
I bought this because I have an 3 1/2 yr old golden doodle. She tears every toy apart within half hour of having it. The only toys she hasn’t is Kong toys. This is a cute toy. She was shredding pieces off the rubber with half hour of chewing it:( I thought it was very similar to the material of Kong toys? She loves chewing it and playing with it but I probably would not buy it for really aggressive large dogs who tear up toys.

My lab loved it too much, too fast…
Color: blue, Color: blue
It arrived an hour ago and my lab has it in pieces within minutes. It kept him busy for a bit though! I’ll give it to him again but I’ll have to sit with him, for sure. No squeak? I guess he just didn’t get to that part of the toy. It felt sturdy but ultimately didn’t pass the test.
