I have a family of antechinuses living with me on the northern bank of the Hawkesbury River near Wisemans Ferry (Dharug National Park) and I'm wondering if there is some natural or harmless repellant I can employ for cupboards and nooks where I routinely find their scat? My latest experiment is naphthalene flakes but I don't much like the smell either! Pepper? Cayenne? Any ideas gratefully appreciated!

Hi Chris, I caught the little creature today. It is an antichinus. WIRES are coming to collect it as I have 2 cats and I want it to survive.

Hi Lizzie,

Based on your description the animal sounds more likely to be a Common Ring-tail Possum, Pseudocheirus peregrinus . The best way to confirm what species the animal is would be to send an image to Search & Discover; sand@austmus.gov.au if you see it again.

Thanks,

Chris

I have seen a small creature in our backyard in West Ryde, Sydney. Our neighbours have seen a similar creature that has a nest, made of leaves, in a large tree near their sun-room window. Could it be a Brown Antechinus? It looks like the pictures I've seen.

Hi Jan,

The holes sound more like the work of Bandicoots and even Kangaroos.

Thanks,

Chris

Antechinus do hop a little more than mice and rats, however the legs do not look like a Kangaroo's. The best way to confirm what species the animal is would be to send an image to Search & Discover; sand@austmus.gov.au if you see it again.

Thanks,

I once saw a mouse with Kangaroo back legs- and it hopped- it was caught in a sandpit, so i picked it up- its face was more pointed than a mouse's and it was greyish and i think lighter underneath- it could run along, but when it went fast it looked like a cross between a mouse and a Kangaroo. This was on the Coorong, in SA. I just saw one today in my backyard, but it looked a little darker than i remember. It looked small for a mouse, maybe it is young- the other one was like a little mouse too- is this the Brown Antechinus?

Does the antechimus dig small holes in lawns? I have several little digs and the antechimus have been seen in my area on the South Coast - Batemans Bay region.

Thank you for your enquiry. The faeces or 'scat' of small carnivorous marsupials such as the Brown Antechinus do look different to those of a House Mouse under magnification. Visible on the surface of the Antechinus scat should be a variety of fragmented insect parts. The scat of rodents such as mice (which feed mainly on dry and fresh vegetable matter) is less defined and more uniform in colour. Like most native mammals Antechinus are often fearful of humans, however there are exceptions to this and I have heard of occasions where people and Antechinus live very close (and very happily) together.

Does Antechinus faeces look any different to house mouse faeces and are they timid like a house mouse or can one get up close to them?
