Hi I am new to forum and need advice ... After losing a beloved best feline friend we have got two 9 week old baby's in which my older cat is not impressed however watches and as long as they don't actually invade her space is tolerant with a bitof hissing ... My sister could on bear to see my special needs children so distraught and turned up with a 5 month old kitten ... Now the older kitten is not so friendly flattened her self out and attacked all the others ... Please help as would like harmony between all of them xx
