当使用Python的turtle库画一只猫的时候，可以使用以下代码：

import turtle

# 创建画布和画笔
canvas = turtle.Screen()
pen = turtle.Turtle()

# 绘制猫脸
pen.fillcolor("gray")
pen.begin_fill()
pen.circle(100)
pen.end_fill()

# 绘制猫耳朵
pen.penup()
pen.goto(-70, 130)
pen.pendown()
pen.fillcolor("black")
pen.begin_fill()
pen.right(140)
pen.forward(50)
pen.left(120)
pen.forward(50)
pen.right(140)
pen.forward(120)
pen.left(150)
pen.forward(150)
pen.left(120)
pen.forward(120)
pen.right(140)
pen.forward(50)
pen.left(120)
pen.forward(50)
pen.end_fill()

# 绘制猫眼
pen.penup()
pen.goto(-25, 40)
pen.pendown()
pen.fillcolor("white")
pen.begin_fill()
pen.circle(20)
pen.end_fill()

pen.penup()
pen.goto(-35, 45)
pen.pendown()
pen.fillcolor("black")
pen.begin_fill()
pen.circle(10)
pen.end_fill()

# 绘制猫鼻子
pen.penup()
pen.goto(10, 0)
pen.pendown()
pen.fillcolor("black")
pen.begin_fill()
pen.circle(15)
pen.end_fill()

# 绘制猫嘴巴
pen.penup()
pen.goto(15, -20)
pen.pendown()
pen.right(90)
pen.forward(25)
pen.right(220)
pen.forward(50)
pen.right(140)
pen.forward(50)

# 绘制猫胡须
pen.penup()
pen.goto(-35, 5)
pen.pendown()
pen.right(75)
pen.forward(90)

pen.penup()
pen.goto(-35, -15)
pen.pendown()
pen.right(90)
pen.forward(90)

pen.penup()
pen.goto(25, 5)
pen.pendown()
pen.left(75)
pen.forward(90)

# 绘制猫身体
pen.penup()
pen.goto(-55, -120)
pen.pendown()
pen.fillcolor("gray")
pen.right(150)
pen.forward(150)
pen.left(90)
pen.forward(50)
pen.left(90)
pen.forward(70)
pen.left(90)
pen.forward(50)
pen.left(90)
pen.forward(70)
pen.left(90)
pen.forward(50)

# 绘制猫脚
pen.penup()
pen.goto(-55, -195)
pen.pendown()
pen.left(45)
pen.forward(40)
pen.left(180)
pen.forward(40)
pen.left(135)
pen.forward(60)
pen.left(180)
pen.forward(60)

pen.penup()
pen.goto(95, -195)
pen.pendown()
pen.right(45)
pen.forward(40)
pen.left(180)
pen.forward(40)
pen.right(135)
pen.forward(60)

# 绘制猫尾巴
pen.speed(4)
pen.penup()
pen.goto(125, -135)
pen.pendown()
pen.right(30)
pen.forward(80)
pen.right(120)
pen.forward(80)
pen.right(150)
pen.forward(60)
pen.right(180)
pen.forward(60)

# 绘制猫颈部
pen.speed(1)
pen.penup()
pen.goto(0, -50)
pen.pendown()
pen.fillcolor("gray")
pen.begin_fill()
pen.left(45)
pen.forward(30)
pen.right(135)
pen.forward(30)
pen.right(45)
pen.forward(30)
pen.right(135)
pen.forward(30)
pen.end_fill()

# 隐藏画笔
pen.hideturtle()

# 关闭画布
canvas.exitonclick()

运行以上代码后，会在turtle图形窗口中绘制一只微笑的猫。你可以根据需要对猫的图形进行进一步调整和美化。
