KEY Success Factors If you would like to read more about the Western Ringtail possum and some carer’s stories, access the web-site: http://www.members.westnet.com.au/ busnet/index.html This care sheet may be copied for educational purposes only. These guidelines are the property of F.A.W.N.A. Inc.W. A., P.O. Box 551, Busselton,W.A. 6280 They were compiled using information provided by experienced carers. Photos: Lesley Jackes The Western Ringtail Possum is listed under Specially Protected Fauna in the Wildlife Conservation (Specially Protected Fauna) Notice, published yearly in the WA Government Gazette. All Specially Protected Fauna coming into care must be reported to a DEC Wildlife Officer. FAWNA information is also available at: http://www.fawna.com.au/index.html ! At first contact, keep the possum secure, warm, quiet and covered It is identified as a ringtail because it has a smooth, furred, tapering prehensile tail with a white tip. The ears are rounded, but smaller than the Brushtail possum. The first two digits are opposed to the other three of the fore foot to enable the ringtail to grip firmly. The pouch is forward opening with four nipples.The weight range is up to 1100gms.All over the South West, their main source of food is the Peppermint Tree (agonis flexuosa), although the exception is the Perup Forest community which lives mainly on eucalypts. Adult Possums - sick or injured Assess the animal and if necessary treat or take it to a vet. To catch and hold an adult possum, it is recommended that a towel be thrown over its head and body. Then turn it over quickly securing its legs in the towel. Protect your eyes, face and hands. Stressed and injured animals often bite and scratch to protect themselves. Every animal in need of care will experience shock. To minimise this, do the following: ! Secure in a carry cage or box with comfortable bedding (wool or cotton). ! Leave with water, peppermint tree leaves and native blossoms. ! Measure feeding formulas according to the possum’s weight ! Put the cage in a quiet, warm or shaded area (depending on the weather). ! Cover the cage lightly with a towel or old blanket and leave to recover from shock. ! Keep the cage dry, clean and make sure there are air holes. ! Handle the possum as little as possible. This care sheet was made possible by sponsorship from Iluka Resources Ltd. ! Be aware of the possum’s natural habitat and living conditions. Treatment for dehydration will probably be necessary. To check, gently pinch up the possum’s skin and if it stays in the fold, then dehydration is present. Other signs are: mouth is not moist inside, eyes not as bulbous as usual (sunken) and not as bright. Offer the possum an electrolyte solution. Many FAWNA members use Lectade. Emergency only dehydration fluid is one teaspoon of glucose/Glucodin to one cup of boiled water. Drip slowly with a syringe into the mouth. Make sure it swallows. If severely dehydrated, ask the Vet to administer fluids. Food These foods are suggested: Peppermint leaves, bottle brush flowers and all other Australian native leaves and blossoms. Give a variety as the possum is unable to roam and find its own. If antibiotics have been administered by the Vet, gut flora needs to be reintroduced. It is suggested that Protexin as a first choice or half a teaspoon of plain yoghurt with the ABC bacteria be offered for a couple of days. Immature possums Flat furred or pouch babies weighing less than 100 gms: These possums are very difficult to rear. It is very likely that possums of this size will not survive but an experienced carer will know better. Fluffy babies (100 gms or more): They usually thrive if the trauma they have endured is not too great. It is mostly fluffy babies that are handed in to FAWNA. On arrival, place in a small “beanie”, natural cotton or wool. Supply a small piece of soft cloth so the possum can hide under it. Warmth is essential in the form of a wheat bag, warm water bottle or heat pad set on gentle heat. Warm up slowly and allow room for the possum to get away from the source of heat if it wants to. Check regularly when setting up the heat pad to ensure that overheating is not occurring. Make sure that the carry cage or basket is secure and that the possum can’t squeeze through the bars. It’s amazing how little space they need to escape. Gutter guard can be used on a carry cage. Follow the same procedures for reducing shock as for the adult possum. Check “An Immature hourly for dehydration and give warm replacement possum that had fluid if necessary. Otherwise offer warm, native been in care for animal milk mix. Try tempting with a pipette and some weeks, then as they start licking, offer a dish of milk for feeding from a lapping. Put the milk into a small shallow dish, lid or bottle containing teaspoon. Remember possums are lactose milk mix”. intolerant. Offer as much as needed and give rests, take time to feed and don’t force. Make up a little more for each feed, to allow for spills. Do five feeds per day, reducing feeds as solids are introduced. Remember that a pouch baby takes only milk. Fluffy babies will need extra foods such as tender peppermint tree leaves and native foods (bottlebrush flowers). Difficult feeders may feed if eyes are covered and only mouth and nose are uncovered. With a damp soft tissue, gently stimulate the genital area to encourage urination. Faeces will be a thick paste and scant. At each stage, be guided by what your possum is telling you. It will let you know when it is ready to move on. They are all different. It may still need one, two or three milk feeds a day, but encourage a natural diet. Housing The type of housing will depend on the age of the possum and its state of physical well being. This ranges from a carry cage with heat, to an inside cage with branches for climbing, to a half size outside aviary cage and then a full size aviary cage. For immature possums, a sleeping box with own beanie is to be provided. Place in the cage young peppy leaves, native tree leaves/ flowers and a dish of water for the night. Do not leave any uneaten milk mix in the cage. For adult possums, transfer to a large outside full size aviary/cage in a sheltered area, when the possum is able to move freely and has recovered some strength. Provide plenty of natural climbing material, a sleeping box and a bunch of young peppermint leaves placed in a tube of water every night with the other foods described. Dispose of any uneaten contents each day to minimise the presence of ants and other insects. Housing requirements are given in more detail in “Minimum Standards for Wildlife Rehabilitation in Western Australia 2008” published by DEC. Release Possums are released only when aged 9 months or more, when independent, healthy and eating a wide variety of native foods. The Western Ringtail Possum is a threatened species and DEC does not encourage their release by carers if they themselves have a release program running. So when your possum is due for release, get back to F.A.W.N.A. and we will let you know the current situation. Soft release in a suitable environment is essential for the survival of the Western Ringtail Possum. Western Ringtails strongly defend their territories and any other adult possum released into them is likely to be driven out or killed. Young possums are tolerated and may find a home if released into an occupied territory. Feeding method and feeding mixtures for immature possums These are Divetelact, Wombaroo or Biolac (most common). If Biolac, possums stay on strength 100. Do not microwave the mix. Milk feed is approx. 10% of body weight per day. For example, if possum is 100gms in weight, then 10 mls per day in five feeds which equals 2 mls per feed. Over feeding can cause severe digestive problems. Make up milk as per instructions. To prepare the milk, mix a little water to break the lumps and then add remainder. Make enough for the day and keep the remainder in the fridge. Use warm mixture, not hot. Keep all utensils clean. To assist a young possum to feed, wrap it snugly, leaving the head free. Put the mouth in the milk and keep the nose out. With the correct angle, the nose will not get in. A tiny spot of honey at the bottom of the dish can be useful for the first feed. Do not continue using it as it will cause diarrhoea. Nests/dreys/sleeping boxes These may be made from flower pots, hanging baskets, small cartons and hollow logs, or nest boxes made out of marine ply. Use your imagination and make it snug with soft bedding, a beanie or cuddle rag and peppermint tree leaf fronds. Ensure it is placed in a protected, elevated corner of the cage on a sturdy platform.
