An Aussie family have been left reeling after their three beloved pet cats died within days of each other. 

Emily Gardner-Hudson, 21, found her sister’s cat Theodore dead when she came back to her home in Crestmead, in Brisbane‘s south, earlier this month. 

The grim discovery was made in a sheltered cat pen in the backyard, but just days later Ms Hudson’s own cat Cuddles also died. 

She said the cat was ‘totally fine’ on the morning of August 8 before Cuddles suddenly began to bleed from her mouth and abdomen. 

‘I have never seen so much blood… it was like a hose and it was the most traumatic thing I’ve had to witness,’ Ms Hudson told Yahoo. 

The shattered family were dealt another cruel blow when their third cat Pebbles suffered the same fate. 

She had to be euthanised after the family was told she had sustained neurological damage. 

The cat was euthanised by specialists as a result of the disease.

‘The feeling is very much still raw for us all, it’s definitely not something we could ever be prepared for… it happened so soon and [was] so horrific,’ Ms Hudson said.

Ms Hudson suspects the cats may have died from rat poisoning after a bag containing rat bait or aspirin was found. 

They believe it was thrown over the fence by an unknown person. 

She said Logan City Council and the RSPCA were notified about the deaths of their beloved cats.  

‘[The council said] there isn’t enough evidence to go by even though we had the vet’s knowledge of the poison and the bag was found,’ Ms Hudson said. 

Daily Mail Australia has contacted the RSPCA and the council for further comment.

Ms Hudson urged pet owners to be keep an eye on their animals even if they live in the backyard and look out for any potential signs of poisoning.

Administering, feeding, laying a bait or harmful substance, with the intent of injuring or killing an animal is illegal in Queensland under the Animal Care and Protection Act.

Anyone convicted of the offence can jailed for a year or fined a massive $48,390.
