You can prevent water entry during bathing by occluding Dolly's ear canals with cotton balls. Water that enters the canals while the dog is swimming or being bathed settles at the bottom of the L, where it's dark, warm and moist, perfect conditions for bacteria and yeast to proliferate.
What's your advice?Ī: Dogs' ear canals are L-shaped internally. My veterinarian suggested I clean her ears after swimming to prevent infections, but I didn't think to ask how. Q: Whenever my dog Dolly swims, her ears become infected. Fortunately, XXY cats are healthy and not at risk of medical or behavioral problems. This XXY condition is rare in cats, which explains why your veterinarian was so surprised to see Joseph's coat of many colors.
#Calico cat female plus
So, a cat with black and orange fur must have two X chromosomes and therefore be a female.Ī male cat may be either black or orange, but not both - unless he has a chromosomal abnormality.Ī calico or tortie will be a male if he has two X chromosomes, which give rise to the black and orange fur, plus a Y chromosome that produces male genitalia. The gene for black fur sits on an X chromosome the gene for orange fur also resides on an X chromosome, but not the same one. Other colors are modifications of the two basic colors for example, gray is the dilute version of black. The two basic colors are black and orange, sometimes called red.
Males have one X and one Y chromosome and are called XY.Īpproximately 20 genes determine coat color in cats. Females have two X chromosomes and are referred to as XX.
#Calico cat female code
Because of the genes that code for coat color, both types of cats are almost always female.ĭomestic cats have approximately 20,000 genes on 38 chromosomes, two of which are the sex chromosomes X and Y. Why is that?Ī: Calico cats have orange, black and white fur, while tortoiseshell cats - "torties" - sport orange and black fur. My veterinarian was surprised when she examined him and confirmed he was a male, because she said calico cats are almost always female. It's relatively unlikely for a cat's unruly behaviour to be down to its fur colour.Q: I adopted a calico cat from a shelter that named him Joseph for his coat of many colors. For instance, some cats become aggressive following castration. However, aggressive behaviour in cats can have numerous causes. Grey and white cats were mostly aggressive at the vet's, whilst calico cats showed their unruly side in normal day-to-day life. Black and white cats were especially displeased when they were touched. More than 1,000 cat owners filled out a questionnaire on the behaviour of their cats for the University of California.Īccording to the questionnaire, tricolour, black and white and grey and white cats are said to have been more aggressive towa rds humans. In a study from 2015, US scientists claim to have found a connection between a cat's fur colour and its character.
There is so far little scientific evidence to support this assumption. It is said that the y are touchier than cats of different colours. This genetic combination is extremely rare and a cat needs a real dose of luck to be born with this unusual fur pattern.Ĭalico cats are considered little divas. The piebald gene makes a red and black agouti cat into a red, black and white calico cat. The size and distribution of the spots are down to chance. The piebald gene (S locus) ensures the white areas in the cat's fur. Agouti cats have fur made up of black and red markings. The pigment eumelanin ensures black fur and phaeomelanin red fur.īoth pigments are present in different proportions and thus result in different colour variations. Cat fur base colours: Black and redĪll cat fur colours, shades and patterns can be traced back to the base colours red and black. The calico's fur also has white.įrom a genetic perspective, both fur patterns have something in common.
The tricolour calico and bicolour agouti cats are often mixed up with one another. How does the calico cat's tricolour fur pattern emerge?
