When Do Wild Baby Rats Leave Their Family
Most baby rats – wild and domestic – volition exist cared for past their mum, which is the best matter for them. However, sometimes equally a rat owner you lot may find or exist asked to intendance for abased babies. What's the best thing to practice if it happens to you lot?
Annotation: although I've never encountered any bug in rearing baby wild rats, it is important that anyone who handles a wild animal takes advisable hygiene precautions, and consults a vet nearly giving rubber treatment for parasites or bacterial diseases that may be carried in your region.

Check they really are abandoned
Wild rat mums leave their nests daily to feed and drink, and so if y'all find a nest containing babies the best thing to practise is to go out information technology lone and go along an eye on it from a discreet distance or check back in a few hours. Mum peradventure waiting nearby for you to go away. If a nest is disturbed, she'll still probably come back once the declension is clear to motion her babies somewhere safer. Every bit with all wildlife, its best to leave babies alone unless you are certain they are in immediate danger or mum can't come up back.
Sometimes you'll know mum is dead, or the nest has been disturbed in a way that identify's the babies at immediate run a risk. Or maybe a well-significant person has already taken them into captivity and is asking for your help. In that instance, what's best?
A surrogate mum is amend than no mum
Domestic rat breeders foster their orphaned litters onto other lactating does if possible. That's because hand-raising rats has a low chance of success, and the babies have a better take a chance of survival with an unrelated mum, even allowing for the risk of her killing them. This is doubly or triply the case if the babies are pinkies – i.e. less than a week sometime and without fur.
Yet, finding someone with a lactating doe willing to foster wild rat kittens is hard, so although it is worth trying, there is a fair chance the rescuer will end up hand-feeding.

How to hand-feed baby rats
First up, ask yourself honestly if you are the right person to do this. It'due south a big commitment. With rats say a week old, y'all are looking at around ii weeks of hand-feeding every 3-4 hours, including night feeds. Some people just skip the night feeds, but it puts the babies at risk of aridity and a much college run a risk of expiry.
Is at that place a more experienced carer nearby who you can enquire for help? Anybody starts somewhere just caring for baby wild animals is by and large better left to trained carers. However, as many wildlife rescues won't have rats, rat owners tin end up plugging the gap.
Essential equipment:
- A milk substitute. I utilize Divetelact, which is a standard milk substitute for baby animals sold by my vet and used past the local wildlife shelter. I know some other rat carers swear by soy-based human infant formula. Either manner, cows milk, or cows milk-based formulas aren't suitable. If yous are caring for very young pinkies, you may as well demand a colostrum supplement – given the urgency with which this would be needed, you might need to beg and borrow from a local wild animals shelter.
- A manner to feed information technology. Rats are too tiny to use a teat bottle. We utilise a wide bore iv line (with needle removed) attached to the end of a ane ml syringe, both supplied by my vet.
- Somewhere safe to live. Babe rats tin't climb until afterward their eyes open, but they do wriggle about. I use a small plastic animal carrier.
- A rut source. It'south essential that baby rats are kept warm, just as well essential that they tin can't get overheated or burned. I use a snugglesafe microwaveable heat pad wrapped in fleece and placed in the bottom of the carrier.
- Bedding. I use a mixture of fleece offcuts and torn up kitchen towel. I cover the nest with another piece of fleece to keep the heat in. Information technology'due south essential not to use annihilation the babies can get tangled in.
- Cotton fiber buds or cotton wool for toileting.
The three things baby rats need
The three things baby rats need are milk, warmth and toileting, so let'south expect at these in plow.
Milk
Advice varies on how oft and how much to feed infant rats. I've found:
- every 3 hours to be well-nigh right for pinkies and
- every four hours for kittens nearer weaning.
We brand up the milk substitute with boiling water in a sterilised egg cup, according to instructions on the brand. Technically it can be kept a while in the refrigerator, only I prefer to brand fresh for each feed every bit information technology is such a tiny amount.
The milk apparently mustn't exist fed hot – it would scald the babies' gullets. I feed information technology when I can put a drib on the within skin of my elbow without feeling it as hot.
There are 2 risks with paw-feeding baby rats:
- letting the milk menstruum likewise rapidly then they aspirate it into their lungs or noses (incredibly common and i of the leading causes of death in babies),
- and getting air in the feed so they cease up with air bloating in their tummies (too oftentimes fatal).
To control the catamenia charge per unit, I use a 1 ml syringe and apply footling if whatsoever pressure to the plunger. It's very hit and miss and basically y'all get good at it with experience equally you conform to each rat's feeding manner.
Avoiding air in the milk is piece of cake enough by making sure at that place are no bubbles in the syringe or tube. Stopping the babies from gulping air every bit they endeavor and latch onto the milk is harder and comes down to having a proficient technique and then they latch on quickly.
How much to feed depends on the size and age of the rat.
- In tiny pinkies, it can be as little as 0.ane ml at a time.
- Larger rats volition feed more vigorously and may have up to a ml in a unmarried feed.
I prefer to feed less milk more often in younger babies, as it gives their digestions a gamble to cope. A big rich milky feed on an empty tummy in a newly rescued pinkie could overwhelm the digestion and impale them. Some people recommend feeding a small amount of sugar water in the first feed before changing to milk. Information technology has to be judged on a instance past instance footing.
Fortunately, pinkies tin can testify us whether they are well fed, considering their skin is so thin, you lot can run across the milk as a band in their tummy. If they have a squeamish milk band after feeding, and then they've had enough.
Aridity can be a big problem in orphaned babies, especially if they have been unfed for a while, or with a carer who didn't practise nighttime feeds. If I suspect dehydration I take babies directly to the vet for assessment for subcutaneous fluids. Aridity tin can exist spotted by gently pinching the peel on the dorsum of the neck. If it tents upwards and doesn't spring back into place so the rat is dehydrated.
Warmth
Pinkie rats tin't regulate their own body temperatures, so a warm nest is essential and common cold is a major cause of death.
That said, you don't want to get the nest so hot information technology causes rut stress (also a major cause of death). I microwave a snugglesafe until it feels hot to my hand, wrap it in i or ii layers of fleece and pop it in the base of operations of my carrier. I so apply other layers of fleece above and beneath the babies to regulate the temperature. I aim for a nest that feels warm and cosy to my mitt, and I besides await at the reaction of the babies. If they are warm to the touch and healthily pink, the nest is about right, whereas any infant that feels cool to the touch needs to be warmer.
I keep the rats living on the snugglesafe in the carrier (reheating information technology every couple of hours) until they have open optics and are moving about. So I move them to a narrow-barred cage (ones designed for mice are ideal) but put a fleece-wrapped snugglesafe with nesting cloth in a cardboard box so they nevertheless have somewhere warm to retreat to.
If a snugglesafe isn't available, I have used a sock filled with oat groats or wheat and microwaved as a oestrus source.
Toileting
Baby rats can't poo and pee for themselves, so it is admittedly essential that their carers help them, otherwise they'll die. I toilet shortly after feeding. I use a cotton wool bud dipped in warm (not hot) h2o, and gently stroke beyond the genitals and anus. It's not always possible to come across the wee, merely information technology's obvious when they've had a successful poo. Information technology is important to stimulate toileting at every feed until you've witnessed each rat toilet independently (unremarkably around 2 weeks, simply they'll show y'all!)
Determination
As you lot can encounter, manus-raising baby rats isn't for the faint-hearted. I've raised 2 litters. The most recent were iv tiny pinkies who were found in a DIY store. They were merely a twenty-four hours or two erstwhile, and quite bluntly had no chance. We were able to feed them and continue them warm successfully, but because they were and so immature when they lost their mum, they hadn't had much colostrum from her, which means they had no hazard to get their allowed system going. They all died by a week old.
My first litter was a happier experience. The babies were virtually 11 days one-time when they came to me, and had been in intendance since around a week old. That gave them a good caput start as information technology meant they had had a week'due south colostrum and milk from their mum, and their immune systems were working well. We nevertheless lost one on the first night, as the previous carer hadn't provided heat or night feeds, and one of the boys was too weak to consume safely. However, we pulled the other iii through (with a little help from my vets who gave subcutaneous fluids to the weakest daughter for several days running), and they lived with us for the remainder of their lives, which turned out to be over 4 years.
