Bioactive & Naturalistic Rat Cage Setup: Methods to Get Began

Making a protected and attention-grabbing cage structure to your rats is comparatively straight ahead. Nonetheless, a brand new motion in pet preserving is difficult whether or not the way in which we preserve rats – in cages, on shallow substrates and with synthetic toys comparable to wheels – is the healthiest and greatest approach to take care of them.

Having the ability to exhibit pure behaviors in captivity is essential to all animal welfare, and rats aren’t any completely different. Rats can spend most of their day of their cage, so with the ability to run, dig, climb, forage, and train alternative of their setting is important to completely realized rattiness. The pure and bioactive motion challenges us to take a look at whether or not our conventional cage set-ups actually meet these wants.

What does “pure” imply in a rat cage?

Pure can have two meanings on this context. The primary is that the rats’ setting permits them to stay an unrestricted life, in a position to exhibit their full vary of pure and instinctive behaviors inside their regular everyday actions.

Another which means refers to not the rats, however to their cage furnishings. Proponents of “naturalistic” rat cages want to take away all plastic, fleece and brightly coloured supplies from the cage and change them with plant-based objects comparable to hemp rope and material, bamboo, coconut shells, coir matting, and naturally picket branches and toys.

The primary definition is an important because it has the most important impact on our pets’ welfare. So long as a rat can specific all its pure behaviors, then they aren’t affected by whether or not their ropes are undyed hemp or vivid stripey cotton, or whether or not their perches are picket or plastic. The one necessary caveat round cage furnishings from the welfare standpoint is that the supplies should meet the rats’ wants, be protected and non-toxic. Past that, it’s right down to human choice.

Nonetheless, there are different causes to take a look at pure cage furnishings – primarily their environmental impression. Rats may not care what their ropes are fabricated from, however undyed hemp rope is more likely to have a a lot smaller environmental footprint than brightly dyed cotton. Equally, plastic in animal toys, whereas not usually detrimental to the animal, remains to be plastic – it must be manufactured in an industrial course of, and can in the future be thrown away and contribute to long-term plastic air pollution. The fleece materials routinely utilized in hammocks and cage liners are additionally fabricated from plastic, and always launch microfibers into the air and washing.

Personally, I’m not going to throw out all my current cage furnishings – sure most of the baskets and containers are fabricated from plastic, and the ropes are cotton – however to throw them away at this stage could be even much less environmentally pleasant than proudly owning them within the first place. I’ll use them and reuse them till they’re not practical. Nonetheless, I’m making an attempt to be extra conscious in something new I add to the cage – for instance, in future I’ll most certainly make my very own ropes from undyed supplies or previous garments, relatively than shopping for new parrot ropes. I’m additionally more and more making my hammocks out of previous t-shirts which are not match to put on, relatively than utilizing fleece material. So, I in all probability will transfer in direction of a naturalistic cage set-up, however it will likely be slowly, following the ideas of decreasing and reusing supplies, relatively than a sudden redesign.

Auditing your cage for pure behaviors

If an important facet of a naturalistic rat cage is a design that enables our pets to precise their pure behaviors, the primary query to ask is how effectively do our current cage layouts stack-up?

Essential pure behaviors are…


That is actually necessary for rats because it maintains muscle energy of their higher our bodies, in addition to serving to them retain abilities in dexterity and steadiness into previous age.

Alternatives for climbing can embody:

  • ropes,
  • branches,
  • cage bars,
  • spaced out ledges or perches,
  • in addition to “climbing frames” (I exploit an previous picket wine rack).

Nonetheless, ladders don’t rely – they aren’t bodily difficult sufficient.


Rats want cardio train identical to we do. In addition they like to run and boing about when they’re excited or taking part in. Many rats solely get a very good run round outdoors their cage (this is among the causes I now preserve my rats in a protected 24/7 free-range room as a substitute), however a cage with a very good sized footprint and a number of ranges can nonetheless enable rats loads of train. Giant wheels will also be helpful, though some rats simply ignore them.


Most wild animals make investments nearly all of their time awake in searching for meals. Consequently, animals in captivity can get bored simply when their meals is delivered in a bowl.

To stimulate foraging behaviors, hiding meals across the cage and scatter-feeding dry combine within the substrate might help, as can puzzle toys and alternative ways of presenting meals comparable to kabobs and pinatas.


Rats love making nests, and while they may make them out of something helpful, they get pleasure from it extra if they’ve alternative – about the place to sleep and what to construct their nest out of.

A great cage structure ought to supply a spread of locations to snooze, and a spread of choices for bedding, from newspaper and kitchen tissue, by way of to bits of material, substrate comparable to shredded cardboard, protected shavings, hay, and even issues like dry sheep’s wool. Offering supplies in such a means that the rats must tear them up, transfer and course of them themselves can also be helpful mental stimulation. My horde are at the moment engaged on a nest made out of a pair of sacrificial curtains. They’ve taken a few foot off the underside to this point.


Digging is commonly an missed conduct for pet rats. We offer tubes they will cover in, and generally a shallow substrate for foraging, however overlook that within the wild, Rattus norvegicus is a largely floor dwelling animal that builds complicated burrows.

A great cage structure will present the chance with a base layer of thick substrate, or with a big digging field. Nonetheless, now we’re beginning to query whether or not the conventional cage bases we give our rats (usually solely 10-15 cm deep) are literally sufficient, or whether or not we have to rethink how we allow them to dig altogether. That’s the place the bioactive a part of “pure and bioactive” is available in.

What’s a bioactive rat cage set-up?

One of many issues with conventional substrates like kiln-dried shavings, hemp, or shredded paper is that they aren’t that good at holding burrows. Rats can dig down, however they will’t construct their very own subterranean kingdom. Standard substrates will also be dusty, and, if the rats pee on them, can get smelly fairly shortly.

The bioactive strategy solves these points through the use of a sterile coco soil that’s stored barely damp. The soil moisture damps down mud and permits the soil to retain its form because the rats create burrows. A soil substrate additionally presents the chance so as to add in rat-safe crops – though in my expertise they don’t are likely to final very lengthy as soon as the rats get at them.

Nonetheless, the soil itself isn’t the bioactive bit – that comes with the clean-up crew (CUC in bioactive care shorthand). These are rat-safe invertebrates like springtails that stay full-time within the soil, and handle cleansing up mould, stray meals and poop. Collectively, the soil and the CUC create a self-cleaning substrate that may be safely left in place for months.

After all, a bioactive set-up does require just a few additional steps to get going – an important is a deep sufficient base, as rats will kick the soil all over the place if there may be not sufficient containment. Most house owners who wish to go bioactive construct their very own deep bases out of perspex – clear partitions have the added benefit of permitting a view into the burrows.

Additionally it is necessary to know that having a clean-up crew doesn’t relieve house owners of all their housekeeping duties. You will need to

  • preserve the soil barely moist (dry soil is dusty and unhealthy for the rats and the CUC),
  • and to flip it a minimum of as soon as per week to forestall ammonia build-up within the tunnels.

That is actually necessary to forestall the rats getting unwell with respiratory illness. Additionally it is essential to nonetheless have litter trays, and to wash the remainder of the cage recurrently. Nonetheless, with some funding within the set-up and accountable husbandry, a pure and bioactive cage setup presents a rewarding new tackle rat take care of rats and house owners alike.
