Awwwww … the Ottawa Rat Rescue is a great place!
and our 2 ADMINs Jorats and Lilspaz68 are also connected to that rescue as are some members on here
Your rats and your cat are very sweet ……… But that is very dangerous
Rats are either predator (smaller animals such as hamsters, mice, birds, etc)
or prey (reptiles, birds, cats, dogs, etc)
so it is never safe to mix them with other species
(rare exception being rats that were raised as nursing infants with adopted siblings who were nursing infants of another species)
It is easy for a friendly animal of another species to react instinctively and in a split second harm or kill a pet rat by mistake.
Also, anyone seeing this picture might think it is ok to put rats and cats together and their rats could be killed when they try it
Mixing rats with animals of another species = risking their lives or the lives of the other animals.
Imo, nothing is worth that.
